Thanks for answer. I am very sad to see that. I had examined samba behavior with tracer and had seen too many poll, fcntl and stat system calls by samba task[ldapsrv] process Elapsed Times for PID 1423, SYSCALL TIME (ns) dup 2653 flock 5811 lseek 33513 geteuid 42747

Hi, I installed Dovecot on FreeBSD 4-STABLE machine and have a problem. MTA is postfix delivering to ~/Maildir, runs perfectly. Dovecot is configured to use plaintext auth, config file is at the end of this mail. When trying to get mail via IMAP, I'm getting the following errors: /var/log/dovecot.log > Aug 24 12:00:35 Info: Dovecot starting up > Aug 24 12:00:51 Info: Login: goshik

Good day oh technical ones . I was running Samba 4 (client only, not using it as a DC so effectively running Samba 3 code from the Samba 4 tree) and, other than a little "Gotcha!" regarding decoding Kerberos PACs, it was all working perfectly. Then recently I had to upgrade, to "4.2.0pre1-GIT-b505111" (I had to upgrade the OS on the server
