Original Issue: IntRAnet Auth: Active Directory first login successful but second failed.
We installed AD 5.0 and were successful in logging in users for the first time. However after logging out then attempting to login again, we got the following error and we do not currently have auto login enabled.
InnerException: Cannot insert the value NULL into column 'UserID', table 'secretdatabasename.dbo.PasswordHistory'; column does not allow nulls. INSERT fails. The statement has been terminated.
Version : 07.01.00 (2676)
SQL Server 2012
Microsoft .NET Framework 4.0.3
When we set AD to auto login, we get the same results.
Today I was looking for anything similar to my "does not allow nulls" problem and found a post from Mark G saying to simply to check allow nulls. Found that here: http://www.dnnsoftware.com/forums/forumid/89/postid/489025/scope/posts
Windows Login works.
