Fields In Users Db Table For Authentication
which fields do you place in your db for user authenication?

for example..:
CREATE TABLE `users` (
`id` INT(11) NOT NULL AUTO_INCREMENT,
`Username` VARCHAR(40) NOT NULL default '',
`Password` VARCHAR(40) NOT NULL default '',
`Lastlogin` datetime default NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `username` (`username`)
) ENGINE=MYISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

i wonder for some more useful fields for software logging/management people sometimes (or seldom :-)) use like:
lastip
createdon
lastlogin
active ('yes', 'no', 'banned') -

Error 1142 - Mes. The Following Occured: SELECT Command Denied To User Xx@hostx.com For Table 'user
When trying to do anything to do with "User Administration" in MySQL Administrator 5.1 connecting to a remote MySQL database, I get the following message when I click on the "User Administration" icon/text in top left frame. Verbatim quote apart from my connection details which I am anonymising):

A MySQL error was encountered. The message is:

The following occured: SELECT command denied to user xxx@hostxxx.xxx.xxx.com for table 'user' (1142)

No I have looked through search and found the following:

http://lists.mysql.com/mysql/134369

Unfortunately that tells me that it has happened to someone else but that's about it. What is one supposed to do with the fix?

I am wondering if this is why I cannot create ordrop any tables with this username at the moment, even though it is the Admin level username....

Mysql User Table?
I have number of customer and they should have different access levels, some would access only few pages. I thought if i create a table:users in my database: maindata-> table: loginuser: will solve the problem, but something is not right when i saw the default mysql user table.

maindata->table loginuser: columns are
user id autoincrement
userfname varchar
userlname varchar
email varchar
userurl varchar
accessgroup (tinyint) = 1,2,3,4
Depending on this value they will access the specific url with.

However after reading code below, I am bit confused about storing all users, should i use default mysql user table cause it has got all privaleges by default ie., insert, del, modify etc. and sounds more secured cause if by mistake users can type admin.php url?

Mysql_connect(): Client Does Not Support Authentication Protocol Requested By Server; Consider Upgrading MySQL Client
I am having an awkward problem with my MySQL installation. I have a number of scripts that access the database from a few different web hosting sites. I have no problem accessing the database from the scripts that I host locally. The scripts that are on an outside server accessing the database gives me a mysql_connect() error.

Locally I use MySQL 5.0 and PHP 5.0. I am assuming that the 3rd party web host uses an older version of PHP and thinking that may be the problem. Is this the possible problem and if so is there a way to fix it without ruining the scripts that are currently working?

Relating User Table With Content Table
I have a mysql table with the curriculum vitae (CV) information of about 50 researchers. I would like each researcher to be able to edit and update his/her information. In order to do this I need to create a membership system for the researchers to access their respective CV page.

Before I do anything I want to plan this out, hopefully with a little help of more experienced developers and programmers. So I am open to any ideas.

This is the thing that stumps me the most right now:

Right now I have a CV table (with all the curriuculum vitae information) and need to create a users table that will somehow link with the CV table. Eventually, what I would like is with a login and password (that they choose) they will automatically open their CV page. These are the questions I have:

What fields in the user table should I use to link the user table with the CV table?
Once that is established, how, by providing their login and password can I direct them to their own page to update? Should one of the fields in one of the tables contain the (already existing) address of their CV page?

How To Log Authentication Failures ONLY?
I am trying to figure out how I can log _only_ authentication failures with mysql.

It appears to me, that I can only either log all queries and mysqld errors, or only mysqld errors?

I have tried in my.cnf:

[mysqld]
log = /var/log/mysql/access.log
log_error = /var/log/mysql/error.log
log_warnings = 1

But this logs every single query made, which I don't want, as it fills up the log files too much.

If I do only
[mysqld]
log_error = /var/log/mysql/error.log
log_warnings = 1

or...
[mysqld]
log_error = /var/log/mysql/error.log
log_warnings = 2

... then I get only mysqld errors, but nothing related to authentication failures.

Is there a way to configure this?

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

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

Authentication Problem On Nonstandard Port
I am running two database instances of mysql (one on a nonstandard
port). After granting users permissions I find that I can access
mysql from other machines only if I use the standard port. When I use
the non-standard port I can only authenticate if I am on the box where
the database is running. Also some previously set up users can
authenticate through the non-standard port (sadly no one knows how
those users were set up). What do I need to do to allow for
authentication on the nonstandard port ex:

mysql -h<HOST> -u<USERNAME> -p
(defaulting to standard port works)
mysql -h<HOST> -u<USERNAME> -P<NON-STANDARD PORT> -p

Connection String Authentication To My Server
I'm having a tough time figuring out the proper connection string to connect to my existing database.

Using:
* MySQL server 4.0 on a remote Linux Server.
* Developing in VS 2005 (VB) on a PC that is apart of our corporate MS domain.
* Downloaded and installed Connector/Net 2.0

Problem:
I'm using the connection string: ("server={0}; user id={1}; password={2}; database=test; pooling=false", server.Text, userid.Text, password.Text)

When executed with userid="sam" the error message that is returned is "Access denied for user: "sam@<mypc>.<corporatedomain>.com"

When executed with the userid="sam@<remotehost> the error message returned is "Access denied for user "sam@<remotehost>@<mypc>.<corporatedomain>.com". No matter what I do, the connector keeps appending my current domain id to the end of the user string.

"sam" is a authorized user for the MySQL on the remote linux host (been using it for years).

Database - User Table - Propagation
I've started a new website and I want to have a database that works with all my other user tables in my other databases. This is my idea.

Background. Example Setup Tree
--Main Page:
-->Forums
-->Mail
-->Collaboration
-->Bug Reporting
-->Etcetera
-->Etcetera
-->Etcetera

*NOTE: Each subsection has it's own database with their own user tables

-------------------------------------------------------------------------------

UserX visits my site. There's a register screen and UserX performs the standard Registration which is then added to the userdb in the usertable.

I want to run a query that will update all subsequent user tables of their own databases.

So, one query or multiple queries will register UserX's info into all those databases.

Once the person is logged into the site, the don't need to register nor login into the other portions of my site, they just click on 'said' link and have access to that portion of the site.

Sorting A Table According To User Criteria.
I was looking for a some kind of simple solution to this issue. The application requires that certain tables should be showed ordered by the user criteria, for example categories. the user will insert a new category and then he could move up or down the item to the position he wants to show it.

In order to do this, I was thinking to add a column, let's call it 'sort_id' this column will save the position of the record. (this is the best i could come up with, I would love any suggestions). This might create some concurrency problems, but since this is an administration module, I don't think more than one would modify the same table at the same time. Anyway, I couldn't find an easy way to insert a new record in the table with the last position + 1.

Table Creation Based On User Login
I'm trying to build a website that will allow the addition of users (w/ username, password, etc.).

That seems simple enough.

But is it possible to set something up (in PHP, for example) that will create a new table in the database for each new user?

Ex. John Smith signs up, is verified, and a PHP script (or Java, or whatever) creates a table specifically for him.

I know I'll need a master table of usernames, passwords, etc. These new tables would store certain user-specific data, such as preferences and other data the user might want to restrict access to.

I know I could store all of this information in a master table, but I'm trying to think ahead. Worst case scenario, if there are millions of users (unlikely, but not impossible), I'd hate to have all that data in one table, but if I have to, I can.
