I faced an error when creating managed account the following :-
An error occurred while getting information about the user XXX at server XXXX.XXX: Access is denied
After search I succeeded to add the account using Power Shell .
After that when I start farm configuration wizard and select the managed account also give me the following error
An error occurred while getting information about the user XXX at server XXXX.XXXX: Access is denied
and also when I want to edit any of the managed Account give me the same error.
