SharePoint User Profile - More than one DN specified for the same profile error in miislcient

Question

Hi All,

I ran the full user profile synch last night and after completion checked the logs and found the below

----------

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.AggregateException: One or more errors occurred. ---> System.InvalidOperationException: More than one DN specified for the same profile.

I went into the

miisclient and found the profile that was causing the problem.

I'm not entirely sure how to proceed from here.

Should I delete this user's user profile in the UPSA?

or does this require an AD account delete?

Any help would be appreciated.

Might or might not be related to an issue i'm seeing with (Failure trying to synch web application 7dfbb1f4-9223-43c3-b817-249f5d9ffc2e, ContentDB 4f8566fb-77bc-43e4-9bad-05be4df5f0e2 Exception message was System.ArgumentException: An item with the same key has already been added.)
