[gentoo-user] Slow Login, Sudo, etc.

[daid kahl <daidxor@gmail.com>]

Hello,

I did a large update a week or two ago (400 packages); system is ~x86.
 It took awhile and needed some cleaning, but in general everything
went smoothly.

However, I noticed that logins, su, and sudo are all responding
slowly.  This was all fixed and fine once I updated my configuration
files, but this week it's acting up again.  Before it was just su and
sudo that I noticed as slow (authentication takes around 20 seconds).
But now even logins are delayed (xdm or command line).

As an example that I timed: su, it takes 20 seconds for the password
prompt to appear, and over 60 seconds for the login to authenticate
(assuming the correct password...it is a little faster to fail).

What package(s) are most likely to be responsible for logins and
su/sudo?  I tried rebuilding (and also downgrading) pam, and I'm
trying some other things now, but no luck so far.

I'm happy to provide any information, but this kind of problem is
nothing I have experience with, so I have no sense of what else to
mention.

Cheers,
