MYSQL :: Passwords / Authentication

Passwords
1. I know in mySql you need a username and a password to access a database. However, can you set a username and password (or even just a password) to access a table or a row?

2. Is there a way you can set a database so you can only add data?

3. is there a way I can have people access values to a database (php) without using a password?

4. is there a way to set up diffrent users (with diffrent permissions) for accessing mySQL data?

5. Any comments about how I can get alot of people accessing a database, from diffrent websites, with keeping i as secure as possible?

Passwords
i've written a windows based from end for a mysql database that will work across a local intranet, it stores usernames and passwords for a reporting system, what is the best way to store the passwords int he db? i.e encrypted or?

Passwords & DBI/DBD
I installed the current stable release of MySQL from RPMs. I used the client
and server packages.

After installing the server package, the RPM printed a note saying I should
run two commands. I only got the first one, which was
# ./mysqladmin -u root --password
I assume this gave the root user a password.

I then downloaded and proceeded to compile the Perl DBI and DBD:mysql
packages. The DBI package installed fine after I also installed the
"MySQL-devel" RPM. Code:

Passwords
I want to store some passwords in a MySQL table. Is there any way of
preventing someone using say COntrolcentre from viewing the passwords.

Passwords
I am just starting out using mySQL. I created some databases and tables and
installed mySQLcc to ease my usage. After about 4 months, I've needed to
make some changes that needed root access. I appearantly wrote down the
wrong password so I couldn't make any changes. In the process of trying to
change the password I think I changed it again and unsynced mySQL and
mySQLcc because now I can't access any of the databases with any user.
Although I can still open mySQLcc, it can't connect to the database. I get
access denied no matter what I do. Is there a way to clear the passwords
and start over? Where are the passwords kept? Or do I have to remove
mySQL and reinstall it and start over?

Transferring Passwords
I tried doing a search but did not find the answer I was looking for.

I just redesigned the database that I had created a few months ago. I broke my one single table up into multiple tables.
My problem is that in my old large table I had a password column that is populated by using Password(). Is there a way for me to transfer the info from that column to my new broken down table set?

I did not create a new database when I broke up the large table, I just built my new tables around it so they are all stored in the same database. I'm not sure if that makes a difference or not.

Is it possible for me to just copy and paste the info from one of the fields into the new table? Or will that break the encryption?

Passwords For Myadmin
I am looking for a way to setup a username/password to myadmin. I made the mistake of showing other the website for admin work and now they are messing it all up.

Inserting Passwords Into DB
I have a couple of questions concerning the insertion of encrypted passwords into a mysql database (4.0)
first, some admins seem to think it's a good idea to feed the password in plaintxt to the db and have the db encrypt and store it. I tend to think this is less secure seeing as there is no seperation between the data and the encrypt/decrypt

so therefore encrypt the password beforehand and I want to insert nand retreive it that way. What type should I be using with the store, and what's the best way to store and retrieve it with that type?

Transferred DB, Now Passwords Not Working..
We just switched hosting companies and transferred 3 of our DB's from the old server to the new. Everything seemed to go alright. Our sites are reading from the DB's however none of the users from our DB can log into the website.

When a user signs up to the site we use the MYSQL PASSWORD() function to enter the users passwords into the DB.

How To Encrpyt Passwords In Database?
I'm making a user login system with PHP/MySQL & when users sign up & such I want their password put into the database & encrpyted... how do you do this?

Encripting Passwords In Mysql
Is there any way to encript a password in a mysql database, so that if anyone looks in the database, they wont know peoples passwords?

Encoding Passwords In MySQL
I am developing a database application in which I store usernames and
passwords. Naturally I want to store the passwords in an encrypted form.
However, just like you see in many web applications, I want to be able
to email the users password back to them should they forget their old
password.

I looked at how to store the password data in MySQL and they recommend
using MD5 or SHA. Both of these appear to be one way encryption
routines. IOW once I encrypt and store the users password there is no
way to unencrypt it.

How can I store passwords in my SQL database such that I can convert
them back to plain text when the user requests them?

Problem With (hashed) Passwords
I my program I have my own login form from which I forward username and password to (ADO)ConnectionString, and then make Connection Active.
But, MySQL Server reports error 'Client does not support authentication protocol requested by server; consider upgrading MySQL client'
Newest version of server (and client) is installed.
Help says that server uses hashed password when user is attemp to connect.
How can I provide hashed password from my application?

User Accounts With Passwords
I am able to connect to the database using users that are not password protected. After updating privileges to use passwords and changing login info(in a php document) I recieve the following error from the php document:

Warning: mysql_query(): Access denied for user 'ODBC'@'localhost' (using password: NO) in c:inetpubwwwrootgindex.php on line 9

Warning: mysql_query(): A link to the server could not be established in c:inetpubwwwrootgindex.php on line 9

I am attempting to connect as 'test'@'localhost' with the password 'test'. If I remove the password, I can connect no problem.

Can't Add New Users & Passwords To Grant Table
I am running MySQL 4.1.7 on my Windows XP system. I can create databases, ect. on the command line, but when I try to run a PHP script I receive the 'Access denied' error message. I have tried using the Grant command to add a new user but nothing comes up when I show SHOW GRANT except the root user. How do I add the new users for running the PHP script?

Security For Shared Server.xml Passwords
I have an ISP that has the server.xml in a shared environment. The server.xml file is where my password is available for database access under connection pooling. I really would like to use connection pooling.

Does anyone know how I can protect my password from being viewed by others using the same server.xml file? I cannot get the administrator to change the protection of the file because others in the shared environment need to be able to view it.

Hide Mysql Usernames And Passwords
I'm trying to have people access a secure mysql database. If they get to a certain webpage, they have clearance to access the database, and we have one password and one username (that the users do not know). Does anyone know how to have it so the people cannot see the cgi script to access the database?

User Passwords Lost On Reboot
Server 2003 | IIS6 | MySQL 4.1.14-nt-max | phpMyAdmin 2.6.4-pl3

Apart from root, I have only 6 databases and whenever I reboot the server, I have to reset the passwords on 4 db's (using phpMyAdmin). Checking the mysql db, user table I note that the 4 that are causing problems have an asterix *preceding the encrypted password. The passwords that do not change were set with the help of a friend using SQL statements.

Mod_auth_mysql Or Mysql Usernames And Passwords
I'm writing a web app that needs a login page. I'm doing the dev on a
windows box although the final version will go on a Linux box. I can't
find any versions of mod_auth_Mysql precompiled for windows and have no
idea about compiling c.source on windows (or anything to do it with).

Is there a good reason I shouldn't store hashed password in MySQL and
call them from Python scripts instead of using the apache auth module
directly?

People Store Passwords In Database
i used to store the password in database using md5() function but there is no way to retrieve the

password back.

Now i want to know that -
is it standard and secure way to store password?
is there any other technique to store password so i can retrive it back?

Passwords, Permissions, And Blank Users
I have Apache 2 server, PHP5, and the latest MySQL installed on my system. I'm currently reading PHP and MySQL for Dummies (I told you I was a newbie) and trying to work through a few of the examples.One thing I noticed when I looked at the "users" table in the "mysql" database is a blank user with all privileges on localhost. I deleted that entry, set a password for my "root" account, and created another account with a non-blank password.

The problem I am having is that I am trying to connect to the database as "root" with a blank password, and it's still working. I then tried a blank user, and it worked. I tried a random assortment of letters and numbers, and it worked.

Switched To 4.1, Now Passwords Work Differently - How To Adjust?
I switched from MySQL 3.23 to 4.1. I used Pear DB but now, it doesn't seem to work so I switched to Pear MDB2.

I used MySQL Control Center to add a new system user to the MySQL user table but the password was like an nd5 hash instead of the old 16 character password in version 3.23.

When I try to connect it indicates it can not connect.

Binary Column Types / Hashed Passwords
I'm building an asp.net application using MySQL as the database. I've created a table to store usernames and passwords. During user creation and authentication - i'm presenting the db with a hashed password value.

When a hashed password is stored in a db - how should it appear in the table?

In the MySQL table I'm using to store username and passwords, it appears as
system.byte[]. The data type is defined as varchar(16), binary. The field is not behaving as it should during authentication - as long at I enter a valid username, the system authenticates me despite a correct or incorrect password value.

Can anyone help me to define the appropriate column type? My application works fine w/ MS SQL but fails w/ MySql. In MS SQL the field is described as:[PWD] [binary] (16) NULL

Packed Passwords In Command Line Programs
I think this is a trivial newbie question but can only be answered by a guru.

In command line programs, why should passwords be packed with the parameter name?

For example for mysqlimport one would write the command like that:
mysqlimport -u user -ppass

Why not just
mysqlimport -u user -p pass

?

Authentication
I'm new with mysql and I feel very stupid for having to ask this but I'm trying to program against it and I don't know what my username and pw are. When I installed it, I put in a pw so I'm pretty sure I know what that is, but what is the username I should be using when trying to execute sql commands against it with php?

Authentication
Is there any config file or update to have MySQL use HPUX authentication or NT authentication. for the Windows apps. (Query browser and MySQL Administrator)

Authentication
i want to make a user that can only see one database here with a seperate limited access.

Authentication
I am trying to set the root password, but all I get is:

$ ./mysqladmin -u root password <newpassword>
./mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'

I have no problems connecting like this:

./mysql -u mysql

In the latter case, I cannot do anything. For example

mysql> CREATE DATABASE one;
ERROR 1044 (42000): Access denied for user ''0'localhost' to database 'MoonlightDB'

Slow Authentication
MySQL V 5.0.18 on SUSE 10.1

I'm not a complete *nix noob, but I sure as hell ain't a *nix or MySQL pro.

This is a new installation. Everything screaming fast. Unless it deals w/authentication.

Try to get in w/SQLyog from W2K locally ... intitial connection takes ~20 seconds. Then everything screaming fast.

Web Server (W03) attempts to connect via MyODBC ... same result ... initial connection takes ~20 seconds. Subsequent queries screaming fast.

VNC into the box at any time ... everything fast. (would seem to eliminate network/connection issues)

Authentication To MySQL
i have one problem with l'authentication to the MySQL;
I am using the language Java and i access to the data-base in following

db = DriverManager.getConnection("jdbc:mysql://localhost:3306/" +
nomeDB + "?user=" + nomeUtente + "&password=" + pwdUtente);

but I do not want insert pwdUtente and nomeUtente in the source-code,
What can i do?

Encryption / Authentication
I need to find out if it's possible to do two things with mysql. The =
first is external authentication, preferably with kerberos5, but PAM =
will work as well. Second, encrypting the data stream. Specifically =
with jdbc connections.

User Authentication
I do know how to create user logins and such.what I need to know is once a user logs in and submits his data (CSV) to Mysql DB,how do i ensure that the data goes into his account.In other words,whats the best way to manage user accounts and control the data that goes into that.

Windows Authentication
I would like to a Windows Authentication with MySQL (similar to the Windows Authentication available for SQL Server).

Does anyone knows how it can be done?

Authentication Protocol
I am trying to run an application using MySQL as a DB, but i am receiving the following error message:
"Client does not support authentication protocol requested by server; consider upgrading MySQL client"
I am using MySQL Client Version 5.0.11
Could someone tell how can I fix this issue.

MySQL And PHP Authentication
I'm getting the following error while trying to connect via php to an existant mysql (local) server:

Warning: mysql_connect(): Client does not support authentication protocol requested by server; consider upgrading MySQL client.
I have latest PHP and MySQL installed.

This seems like the password problem (new password system now) the older was 16 bits right? Thing is... My PHP should support this, its 5.x and I have latest mysql as well.

Authentication Protocol
You have no license for using PerlDesk! DBI connect('perldb:localhost','webuser',...) failed: Client does not support authentication protocol requested by server; consider upgrading MySQL client at lib/PerlDesk/App.pm line 408 Compilation failed in require at lib/PerlDesk/App/License.pm line 3.

Windows Authentication
Can MySQL use windows authentication?
If so, what are the changes to the connection string for this?

Authentication Protocol
I am running winXP, mysql, vb 6.0/vbscript.
when i connect through odbc it gave me the following error.
Run-time error'-2147467259 (800004005)
[MySQL][ODBC 3.51 Driver] Client does not support authentication protocol requested by server; consider upgrading MySQL Client

When i connect this mysql with vb 6.0/vbscript in windows 98 it runs perfectly.

Authentication Protocol
I recently had a crash with MySQL-Max 4.0.5beta in the Windows 2000 Server inviroment. I uninstalled it completely and salvaged the DATA directories. So i decided to go ahead and upgrade the MySQL to Server 4.1.7. But now I get an error message from all my scripts that tell me the following.
Warning: mysql_connect(): Client does not support authentication protocol requested by server; consider upgrading MySQL
Can some one please assist me in fixing this matter. I am very limited in MySQL and have done hours of research trying to fix this matter.

Support Authentication
i have installed php4.4 with iis and mysql5 and phpmyadmin is 2.5 version and mysql administration tool too i get the error client does not support authentication protocol,
i will be very pleased if someone suggest a good workin version for all mysql php and phpmyadmin

Authentication Protocol
I am having trouble with my MySQL database, so when I run a script I receive the following error:
'Warning: mysql_pconnect() [function.mysql-pconnect]: Client does not support authentication protocol requested by server; consider upgrading MySQL client in c:wwwdcdjpaneldatabasedb.php on line 27
Client does not support authentication protocol requested by server; consider upgrading MySQL client'
I understand that it has something to do with old db access libraries. I really don't understand the instructions to be done, so if I could be provided with a full-detail list of instructions on fixing this error, I'd appreciate it.
By-the-way, I looked into the documentation of the MySQL software and looked at the website for support, which was a little pricy for one needed solution.

Authentication Protocol
A problem with MYSQL Front 3.1 that will not connect.
I understand that there is a problem with MySQL changing the password hasing functions in ver 4.
One solution is to start the server with the --old-passwords flag, how do i add the flag??

Best Approach To User Authentication?
So I'm setting up a php/mysql driven website on our company's intranet. I need to setup username's and passwords for different individuals because they all need access to different parts of the site.

Now I'm reading up on how to do user authentication. One way I am reading about, involves creating a username/password table in the database, and when the user attempts to login in some generic php/html form, the php logs into the database using a generic login/password, then checks to see if the user's login/password match up with what is in the table.

That's an interesting way to do it. But the thing that is odd to me is that you actually log into the database using a generic login/password (hidden in the php script) and you would simply have to control what the user has access to in your frontend code, based off their login.

MySQL has it's own user authentication system in place, where you create logins and passwords for the database and control what databases and tables they have access to and control what they can do with them. So why wouldn't you do it this way?

Sorry if this sounds confusing, but hopefully users experienced in this understand where I am coming from.

Authentication / Permission Basics
I have a number of users like 'fred', who can access MySQL 4.1 from %.fredworld.com. He has full access to his own database, fred. No other permissions defined.

What's the best way for me to allow every user to connect from localhost. After reading up on http://dev.mysql.com/doc/refman/4.1/en/connection-access.html I thought the answer might be to do:

insert into user (host, user) values ('localhost', '');
flush privileges;

but this doesn't do what I want. How should I go about this?

MySql / Php Authentication Problems
whenever I try to access mySql, I alway's get the following error:

#1251 - Client does not support authentication protocol requested by server; consider upgrading MySQL client

A little extra info (if needed):
-I just installed php v 4.3.1, apache 2, and mySQL 4.1
-It's all on my laptop (if it makes a diffrence)
-It's on a windows platform

Client Does Not Support Authentication
The problem is that when i browse to http://reception/admin/index.php? and enter username and password I recieve the following message

1251 - Client does not support authentication protocol requested by server; consider upgrading MySQL client

But i can log into mysql using the command prompt
