Network Authentication Login

Network Login Authentication
I was recently asked if it would be possible to use the Network domain username and password (Windows login) in Access 2000/Access 2002/Access 2003? If so, How would this be occomplished?

Basiclly, i want to take the Windows Login (Domain) username and password and implement it into an Access application. Is this possible? If so, How?

Login Using Windows Authentication
Anyone have any great ideas on how to incorporate a login from using the network or Windows login information to authenticate against? ie if my login info was username: p and passsword: q, I want to be able to enter that same information into the login screen of my vb6 program and have it authenticated the same way the network/windows login is authenticated. I know I can get the user and the computer but that really ins't what I need, I also know about checking a table or file, but again, not what I am looking for. Any suggestions, code showing how to implement is appreciated.

Login Using Windows Authentication
sorry for hijacking this thread..

I'm operating a internet cafe. i have a management software (ecafepro) to control all the pc like locking, unlock, restart, shutdown and etc. It have a user login page which can login and verify to the program server (ecafepro server). Currently i'm thinking to add a linux SAMBA file server and map a network drive/harddisk space whenever there is user login using the ecafepro.

linux SAMBA file server will need windows login username and password to match the SAMBA login username and password. So i'm thinking whether can I RESET the windows user login using the user login from ecafepro??


Thanks & best regards,
Max.

Login Form Authentication Problem
I have a user name and password textfield on a form. How do I use these fields in an SQL query? ie SELECT userid from customer where username = txtUserName.

This query is in the record source. Does it need to go anywhere else?

I am using the MS ADO data control component.
TxtUserName is a textfield. This is a ADO(DC) linked database.

Any help appreciated

Visual Sourcesafe Login Authentication
Hello

I am trying to use visual sourcesafe for the first time. i am not sure how the system authenticates VSS.

is the authentication carried out on the local machine where some sort of license file exists or does it need to authenticate with a central server.

at the moment i can see the following screen

Visual SourceSafe Login

i types in my intranet username for the username
and intranet password for the password

it is pointing to database common. when i click on browse the path it provides is

C:program FilesMicrosoft Visual Studio

the checkbox "open this database next time i run Visual SourceSafe" is checked.

when i click ok it says user "foouser" not found

interestingly enough when i input the username as "guest" and try the password "guest" it says

"invalid password" which leads me to beleive it is trying to authenticate from some place, if you guys tell me if it is a central server, i can catch hold of my IT administrator and request him to give me a password or account+ password

Browser Window Authentication/login
Hi All,

Hope this hasn’t come up before – I have searched several times on vbCity, but still haven’t found what I’m looking for. I found this topic http://vbcity.com/forums/topic.asp?tid=5308 but it doesn’t appear to work for my application.

I am using VB via the ShellExecute API to open a browser window and point it to a secure address that needs authentication (username and password).

What I would like to do is somehow pass the login details to the browser window, so it will be automatically logged in.

I tried passing the values like this
Code:http://username;password@www.dummy.com/secure.htm

http://www.dummy.com/secure.htm?user=dummy&pswd=dummy

but these don’t seem to work (I changed the ':' to a ';' to stop the smiley appearing). I know it can be done via winsock or the WinHttpRequest object, but how would it be done with a simple browser window?

Does anyone know how to auto-login a browser window?
Is there a way of sending a browser window the authentication data?

Thanks

Automated VPN/Network Share Authentication
My client has requested the ability to automatically synchronise two datasets located at different sites over VPN.

My current design is to establish the VPN connection automatically and browse the network share to locate the database and commence the synchronisation. However, im unsure how to establish a VPN connection in code and to automate the username/password authentication without the need for the user to enter the details. The emphasis on the design is "no user interaction" therefore I cannot think of a design workaround if this is not possible.

Any help in this matter would be greatly appreciated

Stupid Question? SQL Server DSN - NT Authentication - Network ID Change?
We have a VB Appln running in client machines.

DSN's are set to Windows NT authentication.

But is SQL Server, Mangers (Supervisors) are given DELETE permission. So they can delete a record.

The problem here is the supervisor can only delete a record thro VB application only if he logins Windows. We need him to delete the record by logging on to just VB application (Not Windows Login) on the client machine.

How do you do that? That is changing the Windows login ID thro appln or If question looks really absurd pls suggest any other way to DELETE from client machine.

Backup Database To Network Using SA Login
I need to backup my database to the network. The problem is that I will be doing this while logged in as SA. Is there anyway to get SQLServer to use an actual NT login to attach to the network drive.

How Do We Access Network Folders In PCs That Need Password Login? #Resolved, Thanks#
Hello there everywan ^_^ My first post here in the community ^_^

Here's the scenario:

We're deploying a system in a company that has a win2k server, and we have to put our ms access mdb in one of its shared folder.

Our original plan is to access the folder from remote machines using GetFolder("\servernamepathname") but this presents us an error, since we need to provide login name and password before we can access folders from the server >_<

Anywan out there know how do we automate this in VB code?

Thankies a lot

Windows Authentication VS SQL Server Authentication.
Hi Gurus,

I have a simple VB - SQL Server 2000 application which uses a connection string to connect to the database.

following is the scenarios:

1. when pass connection string with valid sql user id and password, it connects successfully
2. If I am logged in as a valid windows NT user, and don't provide any userid and pwd to the connectin string, it connects.

But when I logged in as a valid windows user, and i pass an invalid SQL userid and password to the SQL server, the ADO still logs me in to the application, by ignoring the invalid userid passed through the connection string. It seems to be logging me in based on my windows NT user id.
I don't want this to happen. I want the SQL server to give first preference to the userid provided in the connection string. But I want to do it without changing the SQL server security to 'Standard security. Is there any way that i can force the ADO to use the SQL server authentication, when the user id passed to the connection string is not the same as the windows NT user id.

Thanks !

Authentication
Is it possible to validate a password supplied by a user on a windows NT4.0 or 2K domain server?

Or

would it be possible to validate the password against the client who should be logged in with the same user name?

I already using a API call can get the currently logged in user.
so all that is left to do is to ask windows to validate it for me.

I am using VBA but i can use VB 5 / 6.

Is this possible

Thanks in advance

- SQL Authentication -
What's the recommended form of SQL Authentication?
