Hey folks,
I'm trying to figure out some details about how ssmtp and LDAP work together. Recently I set up an LDAP authentication system, and one of the uses of this is to authenticate against SSH login to one of our servers. Since this happened, I've been seeing hanging sendmail processes, initiated by cron, that I have to kill in order to get the cron.daily stuff to finish. Interestingly, sendmail (ssmtp in actuality) seems to work fine from logwatch (initiated by cron). I get other emails from this server. But for some of the emails initiated by cronjobs, I see this when I do an lsof:

It looks like ssmtp is getting hung up on authenticating through LDAP or something. I'm guessing this might have somethin to do with PAM settings, but I don't know where to begin. I've searched the web and newsgroups and gotten no closer. I don't know how to figure this out. Anyone have any ideas?
Thanks!
