Delays May Occur During MCMS Authentication When You Use Site Server SQL-based Membership Authentication

If you use Site Server SQL-based Membership authentication through Microsoft Content Management Server (MCMS) 2001, delays may occur during authentication for each request to MCMS pages.

If you are using Site Server SQL-based Membership authentication through MCMS 2001, and the user name is a membership user account that does not exist as a Microsoft Windows NT account, a call from the ReAuthFilt ISAPI filter to the LookupAccountName function returns no results for a long time. This delay has a non-negligible effect on performance for each request. The LookupAccountName function sometimes takes up to 60 seconds to complete in customer environments. When Site Server is enabled for SQL-based Membership authentication, the code for the domain account lookup is not necessary.
