Hello,
This is a known issue reported a while back for ALM 12.0, as per HP QCCR1J77907.
The issue affects all 12.x version of ALM. Seems HP removed the ability to call GetUserPropertiesInSite for every user group except for tdamdin.
However there is a fix, per M02159911: [KM link][1]
*As of ALM 12.XX a new Site Parameter is introduced to control the access to users' details - ''USER_PROPERTIES_ACCESS_LEVEL''.*
*This change is intended to improve the security by controlling whether non admin user can obtain details of users in the system directly or through scripts/API.*
**Fix:**
By default the parameter is hidden and is with value ''ADMINS_MINIMAL''.
Possible values for ''USER_PROPERTIES_ACCESS_LEVEL'' parameter:
''ALL'' - All the fields in users table will be available if requested.
''MINIMAL'' - All the fields in users table except user password will be available if requested.
''ADMINS_ALL'' - All the fields in users table will be available if requested but only when the login user is Site Admin/Project Admin, otherwise error message will be responded.
''ADMINS_MINIMAL'' - All the fields in users table except user password will be available if requested but only when the login user is Site Admin/Project Admin, otherwise error message will be responded.
