The case:

Put in the password, hit enter, the screen goes blue for half a second, then goes back to login screen and carries on logging in as usual.  Drives me mad.


Troubleshooting steps done already:

It doesn't happen with a fresh Lion installation, nor if booted into safe mode.  On the machine in question it also happens to new user accounts.

I've removed all login items, including Startup Items, Launch Daemons and Agents, I've compared system login plists with a fresh Lion installation - can't see differences.  I've removed Little Snitch and PeerGuardian (no more third party kexts).

I've done disk maintenance with DiskUtility and even tried DiskWarrior, cleaned caches, etc.


Smc and Pram have been reset several time (for another issue), not that I would have expected them to work, but you never know.


Any ideas would be gratefully received.
