Logscape will import details from Active Directory using the SAM-Account-Name or the uid from a normal LDAP Directory Service. A user must use this to gain access to the system; but this can be reconfigured to use a different attribute on a user ldap object by setting a system property.
Looking at Active Directory we see
So for example if we wanted our users to login with their userPrincipalName we would use the system property
-Dldap.user.field=userPrincipalName
The results of this are that the users now login with the userPrincipalName as listed in Active Directory rather than with their sAMAccountName(default)
