Commvault -Active Directory configuration fails with User does not have access to the page

Commvault -Active Directory configuration fails with User does not have access to the page

When I click on configure Active Directory on the Command center, I get the error message, “User does not have access to the page.” And then the command center stopped responding. The Commserve version is 11.36.55. 

the solution is very easy, go to the Manage > Customization > Navigation preferences and click to Active Directory.
