PROBLEM: The Impact Browsing Service was unable to process this request
.../ImpactRESTful/ImpactBrowsingService.svc/users/user@domain+com -> User is not authorized for access.
User is receiving them when going into the Browser and when trying to do a project number query on Enterprise.
SOLUTION:
This can be caused by LDAP issues, like if you find a difference in the U_LOG_NAME value between CENTRAL and his LOCAL db, issues will occur.
For example, if a user is johnsmith@abc.com in his LOCAL db andjohnsmith@ad.abc.com in CENTRAL.
