## Symptoms

- * The procedure in SK114856 � How to select an alternate AD field for DynamicID in Mobile Access does not work for Remote Access VPN clients.
* After modifying the attribute mapping, the user interface displays only the Email field instead of the expected Phone Number field.

## Cause

DynamicID supports querying a single Active Directory attribute for identity retrieval.  
Changing the parameter PhoneNumberAttr to email in GUIDBedit causes a conflict because the system attempts to use the same attribute for multiple lookup purposes. This creates overlapping queries and leads to unexpected UI behavior where only one field is shown.

On GUIDBedit, attempting to change the PhoneNumberAttr to "email" (Screenshot #1) results in the user only seeing email field (Screenshot #3)
