Are you using pam_afs_session? We've just discovered that when that is
enabled in the su stack, becoming root takes a very long time, whether
or not you have set the minimum_uid or not. The simple solution is to
not run pam_afs_session in the 'su' stack.
More investigation is required into what's actually going wrong, but
nobody here has had a chance to do so yet. Given that just removing
pam_afs_session from the su stack gives us the behaviour we want, I'm
not sure how much more investigation we'll end up doing.
It might be worth speaking to Russ to see if anyone else is seeing
this problem, or he might chime in here.
