You can delete user groups and users from advanced security at any time. You can't, however, change the name or description for groups defined by UltraTax CS, which include the $Administrators, $Guests, and $Unauthorized Users groups.
$Administrators
: Members of this group can access all areas of UltraTax CS. You can't modify privilege settings for this group.
$Guests
: By default, members of this group can access any area of UltraTax CS that was allowed with standard security options. However, you can modify the privilege settings for this group.
When you enable advanced security options, standard security settings are transferred as privileges for the $Guests group. Advanced security options are available in the
Setup
,
Security Configuration
,
Security
tab.
$Unauthorized Users
: Members of this group are denied access to all areas of UltraTax CS. You can't change privilege settings for this group.
