Symptoms:
Users trying to authenticate to UW are getting stuck with the profile loading animation.
For the SCA profile, this is the filling cloud animation.
For the Universal Profile, this is the spinning cursor animation.
Older Profiles, such as the webOS profile may give a nullPointerException error.
Issue:
This appears to be specific to 6.4.0 and Active Directory.
The issue comes from the users not being assigned any individual links. They instead inherit all of their links via Menus assignments. When the menu generation part of the profile code is unable to find any links assigned to the user, it gets stuck and does not finish processing.
Solution:
To workaround this , until the issue is resolved in a future release, is to assign at least one link to all of the users. This can be as simple as assigning the logout link/tile to the OU that all user objects reside in.
As long as the user has at least one link that they inherit, the menu generation process is able to properly finish building the user's menu structure.
