I am getting "500 Internal Server Error – The target principal name is incorrect." after entering username and password on ISA logon page.
Here's the senario:
Windows 2000 Server GC
SharePoint Server: Server-01.internal.domain with commercial SSL cert as sharepoint.mypublicdomain and AAM configured on SharePoint
ISA 2006 with public IP nat to internal IP, with the above SSL imported - Authentication use LDAP
Most configurations are based on MS KB268368 and everything seems to work fine until I present the ISA logon screen with a username and password, then I got "500 Internal Server Error – The target principal name is incorrect" - Please help!
