sAMAccountNames in Active Directory

Internally, Active Directory (AD) uses several naming schemes for a given object. In the case of a User, two fields are of particular relevance: sAMAccountName (SAM-Account) and userPrincipalName (UPN).

sAMAccountNames

UPNs

Current Limitations

Authentication / Auto-Import - Allows up to 20 characters (sAMAccountName)

The component that Pleasant Password Server (PPASS) uses for Auto-Import searches via sAMAccountName, not UPN. This means that PPASS will be unable to find users using long usernames, regardless of whether they exist.

Work-Around: Some customers have found a work-around by using the Directory alias ('@alias') as a suffix, for example, username@alias

Manual Importing - Allows 20 or more characters (sAMAccountName/UPN)
