Hi all, I an attempting to add an additional attribute upon the first login for user accounts and I am a bit lost. The way I am testing this is with postauth query. postauth_query = "INSERT into ${authcheck_table} (id, UserName, Attribute, op, value) values('', '%{SQL-User-Name}', 'Calling-Station-Id', '==', '%{Calling-Station-Id}' )" This works great but it adds a new record every time the user successfully authenticates. Not a problem really but there are also users I don't need to lock to a caller id. I tried using postauth_query = "UPDATE in various ways but I just can't get my head around it. If I manually create an entry in radcheck for a user with the attribute "Calling-Station-Id" and a "NULL" value, then the user can't login obviously. Does anybody have any ideas how to have this attribute somehow dynamically created when the user first logs in if they are a member of a group and ultimately not create it if the record already exists? Any ideas or pointers greatly appreciated. Thanks Shane
