note 73978 added to function.imap-lsub

The Apache's PHP Imap module crashes when running in a chroot, and /etc/passwd isn't present (relative to the chroot). It is enough to have the UID's line Apache is running with present in the passwd file (the shadow file isn't required). Symptoms: Calling this function results in a SEGFAULT. In your syslog (if it was properly set up for the chroot) you can see lines like these: Mar 19 01:07:13 * *: imap-login: Login: user=<*>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Mar 19 01:07:13 * apache2[24918]: IMAP toolkit crash: Unable to look up user name Mar 19 01:07:13 *: IMAP(*): Disconnected Remark: In particular this causes failure of login attemptf in HORDE3+IMP4.
