TMS cannot seem to scan the user to check the user group memberships, therefore I cannot apply any additional permisions outside the TMS default group.
I do get the following error:
13:48:03,186  WARN Tandberg.TMS.Framework.Service.UserGroup.UserGroupService - Failed to find the groups for user user001: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
at ActiveDs.IADsNameTranslate.InitEx(Int32 lnSetType, String bstrADsPath, String bstrUserID, String bstrDomain, String bstrPassword)
at Tandberg.TMS.Framework.Service.UserGroup.UserGroupService.FindUserGroups(String username, String userdomain)
I am using a LDAP browser and can get into the AD/LDAP using the same credentials configured for TMS to use.
