I have a group created in Active Directory. This Group contains 3 users. For some strange reason one of the user within the group can't select from specific type of SCHEMA whilst the 2 other users can select from the same schema I ran some test EXECUTE AS USER for the other 2 users and everything seems fine except for that one user and i get the following error:
Msg 229, Level 14, State 5, Line 4 The SELECT permission was denied on the object '', database 'Somethng_Database', schema 'sch'.
