Yesterday Night, One of my team member called & report that some users are getting below error no. 1 while connection to SQL server & error no. 2 while trying to open Management folder.
Error 1 : Cannot display policy health state at the server level, because the user doesn’t have permission. Permission to access the msdb database is required for this feature to work correctly.
Error 2 : The server principal “xxxx” is not able to access the database “msdb” under the current security context. (Microsoft SQL Server, Error: 916)
Analysis & Resolution : -
Most suspicious thing was, some users are facing issue & some user are working fine. When I goes into depth, I have found that user have super rights on SQL Server & on MSDB are working fine.
That means, it is clearly a permission issue but it is effecting random users in bulk.
Reason in my case : CONNECT permissions are denied from PUBLIC role.
Query to check CONNECT permissions :-
SELECT USER_NAME(P.GRANTEE_PRINCIPAL_ID) AS PRINCIPAL_NAME,
DP.TYPE_DESC AS PRINCIPAL_TYPE_DESC,
OBJECT_NAME(P.MAJOR_ID) AS OBJECT_NAME,
P.STATE_DESC AS PERMISSION_STATE_DESC
FROM SYS.DATABASE_PERMISSIONS P
INNER JOIN SYS.DATABASE_PRINCIPALS DP
ON P.GRANTEE_PRINCIPAL_ID = DP.PRINCIPAL_ID
WHERE P.STATE_DESC = ‘DENY’
We have 2 possible solutions :-
1) Provide connect permissions to all user sepratly
2) Provide CONNECT permission to PUBLIC role
We have resolved the issue by running below command. Connect permissions was reestablished on PUBLIC role.
GRANT CONNECT TO PUBLIC
