WARNING: Possible UAM auth failure with recent MS updates

Ran some updates against our domain controllers 2008 R2 serving as RADIUS for UAM on latest IMC 7.1 patches. 

 

As soon as these updates were applied and rebooted users could no longer authenticate via 802.1x on wired switches via PEAP with the virtual computer and MSM controllers using DCs as RADIUS servers.

 

 

This error was in the authentication failure log:   E63118::Domain controller connect error

 

After rollback of these updates authentication was restored. Not sure which one(s) are the patcheswe applied:

 

Cumulative Security Updates for IE 10 (KB3065822)

Security Update (KB3057154)

Security Update (KB3067505)

Security Update (KB3067903)

Security Update (KB3068457)

Security Update (KB3072630)

Security Update (KB3072633)

Security Update (KB3079904)

Update (KB3040272)

Update (KB3054205)

Update (KB3065979)

Update (KB3065987)

 

We experinced this previously in Dec 2014, but subsequent updates went ok - until now
