On WAM UI installation and able to log into the WAM UI, but below error is seen:
Unable to establish administration context
The above error is displayed when the WAM UI is able to Authenticate the User; since the User is a valid user in the Administrative User Directory, however, the given user has not been granted appropriate privileges in the eXtended Policy Store.
Solution
->login to the WAMUI with an administrative user account that has the privliges to create administrators and create a new administrator.
->The new administrator has to point to this user and should be granted appropriate privileges.
Note : If you do not have access to the WAM UI, you can create the administrative user account manually via the XPSSecurity tool. For more information on creating an Administrator account with the XPSSecurity tool,
