8865 through MRA creating Active directory account lockouts

We have this issue too. Has anyone come up with a way to make it stop after a few wrong password attempts?

Same here. AD account gets locked and such a headache for 700+ MRA users when password changes are required so often.  Cisco, any advice?

If you have a version of CM and Expressway that support activation codes for phone activation I would recommend you to switch to this as it decouples the use of user credentials.
