Issue: Unable to enroll Lync user.
Error: Enable-CsUser : Cannot open database "xds" requested by the login. The login failed. Login failed for user '...'.
While enabling user for Lync, getting above error message. Even user has Lync admin permission however getting above error.
I have CsAdministrator group permission however still getting above error while enabling user for Lync.
When I checked it properly then I found resolution.
Basically you must have of a group permission from CsUserAdministrator, CsServerAdministrator or CsAdministrator. Apart from that you must have RTCUniversalServerAdministrator group permission in order to enroll the Lync user or update data to “xds” database.
I have added my user to RTCUniversalServerAdministrator group and run the following command again.
C:\> Enable-CsUser –Identity “mydomain\Baluilag” –Registararpool “Lyncpool01.mydomain.com” –SipAddressType “EmailAddress” –SipDomain “mydomain.com”
Now user got successfully enrolled for Lync.
