Symptoms
We have several users that cannot work in ANY app that uses K2 - they suddenly lost all their group memberships
Diagnoses
When a user loses its AD group memberships what could be the cause here.
When K2 tries to retrieve user info from AD it logs:
IdentityServiceError","IdentityService.ProviderCacheIdentity:RoleProvider.GetUser","64007 Provider did not return a result for user.
What could be the cause of this error ?
Resolution
Please check to see if the group being used in question has any symbols within it. Best place to check this is from AD itself.
