Web Proxy loses authentication with Active Directory

jreverman
Every 7-10 days, our proxy stops working and shows this error in the proxy log:

"function="read_winbindd_response" file="auth_adir.c" line="210" message="epoll_read_until: Transport endpoint is not connected"

Going into Single Sign On tab and re-authenticating to the domain fixes the issue.

Odd thing is, this only affects the proxy. I can still log into the UTM9 webadmin with my domain credentials while this error is occurring.

We are on version 9.002-12. 

this only began after we upgraded to UTM9 a few weeks ago. 

No errors on my domain controllers. Its as if the UTM9 is losing its trust with the domain and needs to be re-established.

Any help is appreciated.

    I think it doesn't affect logging in with your domain credentials because winbindd isn't used for that.  You definitely should Up2Date to 9.003, and that might solve the problem.  I'm guessing that rejoining the domain restarts winbindd.  In any case, this is a different issue with winbindd than we saw discusssed here earlier this year, so I'd suggest having your reseller open a support ticket to have Sophos take a look at your box if the Up2Date to 9.003 doesn't fix you up.
