I am getting following error in the UserApp for one of the workflows after
I select the recipient:

Provisioning application error:
Error Message:

This was working fine till yesterday and suddenly we started getting this
error. No changes have been done. The attribute (aigADUsername) is there
in the schema since months and we started facing this problem just today.

Any help is appreciated. Thanks.
