Authentication / logins

  • Having a problem with users connecting...

    We have windows groups set up as logins such as

    Domain\U1B-123

    Domain\U1B-456

    Domain\U1B-789

    They are users in various databases such as

    db1 ... U1B-123

    db2 ... U1B-123

    db1 ... U1B-456

    db3 ... U1B-456

    db1 ... U1B-789

    We previously had 456's default db set to db1.

    All other logins use db2 as default.

    We pointed 456's default to db2 as well, then we take db1 offline.

    Now, everyone that is a member of 456 cannot connect to the server. The specific error msg: ""

    The server principal "DOMAIN\U1B-456" is not able to access the database "db1" under the current security context.

    My disconnect here is, why is it looking at db1 in the first place? :unsure:

  • How are the users connecting to the database? is this an application using ODBC/OLEDB, SSMS, something else?

    Is it possible that there needs to be a change on the user side as it may still be pointing to DB1?

  • They are connecting in a number of ways, each fails.

    I'm testing it using

    "EXECUTE AS LOGIN = 'DOMAIN\UserX'

    blah blah...

    When a 'real' user tries SQL Management Studio, it fails with the same message.

    As does the .NET application they're trying to use.

  • Bear with me, have you checked to see wha the system table says:

    select * from sys.server_principals

    I can't recreate your problem, so I am having to guess here.

    Not sure what you're looking for...

    But...

    Name: U1B-456

    Principal_ID 355

    sid 0x0000

    Type G

    Type_Desc WINDOWS_GROUP

    is_disabled 0

    create_date 20090715

    modify_date 20090715

    default_database_name MASTER

    default_language_name us_english

    credential_id

    Neat huh?
