How to get Pre-Windows 2000 user from LDAP login user

HI All,

I have a workflow where I put data in a SQL DB. I put the LDAP login name [ Server.getCurrentLdapUser() ] as a string to the DB. My problem is now, that I need the login ID in the Pre-Windows 2000 format. I work with SQL Reporting server and this one is useing Pre-Windows 2000 format.

Could I get help to convert the LDAP (UPN) format to Pre-Windows 2000 format ?
