Error: Login failed for user ????

P: n/a
Please Help me. I've got a .Net 2003 program that attaches to a SQL Server
machine and I'm getting the above error when a user tries to log in. The SQL
server is setup to use Windows Auth. and I have added the new user to the
database and have given the user access to the database for the app. But
everytime I try and login using this users ID, I always get the error:
Login failed for user Christian.Gaut
If I login using my userid and password, the program works fine, but if I
login (into windows) as the user and try it again, same thing happens. I
tried putting the userid and password(windows) in the connect string, but
that is not helping either. Now, in the user properties of the database, it
won't allow me to change the password for the user (I guess cause I'm using
Windows Auth). So should I leave the password blank in the connect string?
Any help would be great, thanks again for taking the time to stop by.

Can u post the connection string you are using?

Apr 4 '06 #2

P: n/a
The connect string is as follows:
"User=Christian.Gaut Password=??? packet size=4096;integrated
security=SSPI;data source=BACKUPSVR\BKUPEXEC;persist security
info=False;initial catalog=NF_Inventory"

Now I've only put the userid and password here for testing only. I can leave
that in, and login into my machine(using my ID) and it will work. Any ideas.
Thanks

Can you explain this:
If I login using my userid and password, the program works fine, but if
I login (into windows) as the user and try it again, same thing happens.

Are you logging into a domain?

If you are using SSPI, you do not need to enter a specific Username and
password. If you log onto the domain, you may need to have the name
qualified in the database's users list; <domain>\<user>.

Sorry about that Chris.
We are running on a domain. If I'm using Windows Auth, is the Userid and
Password in the connection string even used?

Ok here is what I have so far:
I login Windows(using my UserId and password), Run application, I can get
into the database with any problems.

I Login Windows(Using the Users ID and Password). In otherwords my
client(co-worker, ect). App starts, but as soon as it tries to access the
database I get the following error:
Login failed for user 'NARCO??????\Christian\Gaut'.
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

I also wanted to know if any Windows security setting could cause SQL Server
access problems. For example, the user that I'm trying to get access for,
will not have admin rights to his machine, as will most users here. Could one
of these settings be causing problems with SQL Server since I'm using Windows
Auth security in SQL Server. Thanks again.
Michael
P.S. I'm researching now to try and find the answer to my problem, and the
above question came from one of my readings.

Make sure you add users to the server as
"NARCOFREEDOM\christian.gautier" It will not detect user
"christian.gautier" the same as user "NARCOFREEDOM\christian.gautier"

Hi Everyone,
Here is some additional info that might help. I have the follwoing setup in
Enterprise Manager.
Server -> Security -> Logins -> General Tab
The name is listed as 'NARCO??????\christian.gaut
The properties for this user are set as:
Windows Authentication
Domain = NARCO?????? (but grayed out)
Security Access = Grant
and the default database is set.
Server Role Tab:
Nothing set here.
Database Access:
Only the database that needs accessing is checked for permission.

Now if I look in the follwoing
Database -> Users (Users for this database)
The name is christian.gaut and the Login Name value includes the domain and
has Permit access to db.
The properties are set as followed:
Permit in Database Role:
Public, db_owner, db_datareader, db_datawriter are checked.
and for the permissions I set every possible option (Select, insert, update
and delete) for all the tables and SP's.

I hope this helps.

Hi Everyone,
I have a question about something I read in the online help.
<Quote
When a network user tries to connect, SQL Server uses Windows-based
facilities to determine the validated network user name. SQL Server then
verifies that the person is who they say they are, and then permits or denies
login access based on that network user name alone, without requiring a
separate login name and password.
/>
Does this mean that the password needs to be set in SQL Server. I ask,
because, since I have Windows Auth set for the database, I can't change any
of the users passwords.
I was trying to do a test and just setup the db so that it uses only SQL
Auth, but when I try to change it to SQL Auth I get an error:
SQL Server registration failed because of the connection failure.
Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server
connection.

I was thinking of changing over to SQL Auth to make it easier (If I've got
to go through this each time I add a new user). What do you all think? I've
heard that Windows Auth is better than plain SQL Auth. Why? How about
creating a single userid and password on the server and user that combo in
the connect string to connect to the db. I hope I can get Windows Auth to
work, so I won't have to go in this direction. Thanks for any help & comments.
Michael

You may want to post some of these questions to the SQL server group,
they may be able to help you a little more.

Apr 4 '06 #11

P: n/a
you sure you're not trying to double - hop authentication or anything
like that?/

Apr 5 '06 #12

P: n/a
if you have AD GROUPS setup you wouldn't need to add a new user to
anything; just add the group.

that way you create the user in one place (in Windows AD) and you're
done
