How are user names matched via the various methods
PowerShell - Match via the 'Match AD Account To" field in the 'User Provisioning' tab located in Settings
CAS Server - SMTP address only
LDAP - short name, employee id, full name, then CMTe tries to match on internet address from the value in Notes Migrator.nsf. Matching stops after finding the first successful and unique match. Employee ID is matched against the SAMAcountName attribute.
