In previous versions of vRealize Operations it's been possible to login by providing only the username without the domain suffix when the
userPrincipalName option has been selected in the Active Directory authentication source.
This caused massive reads per login from the database when there were large numbers of imported AD users, since the whole user list would be retrieved from the database and iteration was done over the complete list to find the required user.
Starting in vRealize Operations 7.5, a single query per login is performed using the full format,
[email protected], which positively affects performance.
The limitation coming with this change means that the login will only be successful if the username's domain suffix matches the domain name specified in the
Base DN option. Otherwise, the full username with domain suffix is required during login.
