the above mkdir() Dovecot should chdir() to user's home directory. So if
LDAP returns user's home directory, I'd think the chdir() causes
automount?
There must be some sort of race condition happening here with
automount. I modified the code in mail-process.c to repeat the chdir
(until CHDIR_TIMEOUT) until it succeeds, and it usually succeeds on the
2nd try.
Eg (I've added some additional logging for debug):
May 14 16:21:04 testbed dovecot: [ID 667285 mail.info] try 0 of
chdir(/home/adent)
May 14 16:21:04 testbed dovecot: [ID 107833 mail.info] imap-login:
Login: user=<adent>, method=PLAIN, rip=xxx.xxx.xxx.242,
lip=xxx.xxx.xxx.242, secured
May 14 16:21:04 testbed dovecot: [ID 791996 mail.info] chdir returned -1
with errno 2
May 14 16:21:05 testbed dovecot: [ID 667285 mail.info] try 1 of
chdir(/home/adent)
May 14 16:21:05 testbed dovecot: [ID 791996 mail.info] chdir returned 0
May 14 16:21:05 testbed dovecot: [ID 107833 mail.info] IMAP(adent):
Disconnected: Logged out bytes=23/104
I still have no idea why this is happening. A simple standalone C
program with the alarm/setegid/seteuid/chdir bits (excerpted from the
original mail-process.c ) works just fine.
