A new registry DWORD entry, AllowAzIfUserDisabled, is introduced up from version 12.5. The key must be set under
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Netegrity\SiteMinder\CurrentVersion\Authorization
By default its value is 0.
If its set to 1, a user will be allowed to proceed further even though the account is disabled in the Authorization directory.
The value is not set by default (and 0 is assumed).
In case it is needed it must be created accordingly
