hello,

i new to list but i need little help. I need only imap (later pop3),i have own checkpassword and own user/password database. i'm using last version v1.0.rc10

But i have problem with auth, user is authorized but cannot login, here is log:

dovecot: Oct 17 15:00:36 Info: Dovecot v1.0.rc10 starting up dovecot: Oct 17 15:00:40 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip=10.0.0.1 rip=10.0.0.13 resp=AG1kdgBza29sYTY2Ng== dovecot: Oct 17 15:00:40 Info: auth(default): checkpassword(lampa,10.0.0.13): Executed: /usr/local/checklocalpwd/checkpassword.pl /usr/local/dovecot/bin/dovecot/checkpassword-reply dovecot: Oct 17 15:00:40 Info: auth(default): checkpassword(lampa,10.0.0.13): Received input: userdb_user=lampa userdb_home=/home/_mail/lampa userdb_uid=65534 userdb_gid=65534 dovecot: Oct 17 15:00:40 Info: auth(default): checkpassword(lampa,10.0.0.13): Received no input dovecot: Oct 17 15:00:40 Info: auth(default): checkpassword(lampa,10.0.0.13): exit_status=0 dovecot: Oct 17 15:00:40 Info: auth(default): client out: OK 1 user=lampa dovecot: Oct 17 15:00:40 Info: auth(default): master in: REQUEST 1 17950 1 dovecot: Oct 17 15:00:40 Info: auth(default): master out: USER 1 lampa user=lampa home=/home/_mail/lampa uid=65534 gid=65534 dovecot: Oct 17 15:00:40 Info: imap-login: Internal login failure: user=<lampa>, method=PLAIN, rip=10.0.0.13, lip=10.0.0.1 dovecot: Oct 17 15:00:40 Error: Logins with UID 65534 (user lampa) not permitted (see first_valid_uid in config file)

i think that problem is that uid and gid is set to user nobody instead 508 and 502 (user lampa , end of message is passwd file)

uid 65534 is user nobody (used in auth section in conf, if i set it to root everyhting is ok)

this is my config:

base_dir = /var/run/dovecot/ protocols = imap listen = 10.0.0.1 disable_plaintext_auth = no

log_path = /var/log/dovecot/dovecot.log info_log_path = /var/log/dovecot/dovecot.info log_timestamp = "%b %d %H:%M:%S "

ssl_disable = yes

login_dir = /var/run/dovecot/login login_chroot = yes login_user = dovecot

mail_debug = yes mail_log_prefix = "%Us(%u): "

verbose_proctitle = yes

first_valid_uid = 508 last_valid_uid = 508

first_valid_gid = 502 last_valid_gid = 502

protocol imap { login_executable = /usr/local/dovecot/bin/imap-login mail_executable = /usr/local/dovecot/bin/imap }

auth_executable = /usr/local/dovecot/bin/dovecot-auth auth_verbose = yes auth_debug = yes auth_debug_passwords = yes

auth default { mechanisms = plain passdb checkpassword { args = /usr/local/checklocalpwd/checkpassword.pl }

userdb prefetch { }

user = nobody }

in file i must comment out chdir $home (program was unable to chdir) i think due to chroot

/usr/local/checklocalpwd/checkpassword.pl: #!/usr/bin/perl

use POSIX; use strict qw(vars);

my $PASSWD_FILE = "/usr/local/qmail/control/passwd2";

%ENV=();

my($len, $buf); open (USER, "<&=3") || _exit(2); $len = read(USER, $buf, 512); close USER; _exit(2) if $len < 4;

my($user, $pass) = split /\x00/, $buf; $user = lc $user; $buf = "\x00" x $len;

my $cwd = getcwd;

my ($passwd, $uid, $gid, $gcos, $home, $shell) = "";

open F, $PASSWD_FILE || _exit(111);

while (<F>) { if (/^$user:/) { ($user, $passwd, $uid, $gid, $gcos, $home, $shell) = split(/:/); } }

close F;

_exit(2) unless $uid;

if (crypt($pass, $passwd) ne $passwd) { _exit(1); }

$ENV{USER} = $user; $ENV{UID} = $uid + 0; $ENV{HOME} = $home; $ENV{SHELL} = $shell;

_exit(111) unless $ENV{UID};

#chdir $home || _exit(111);

$) = $gid; $( = $gid; $> = $uid; $< = $uid;

exec @ARGV; _exit(0);

here is passwd/user file: lampa:HSExFJNuwlKvk:508:502::/home/_mail/lampa:/bin/false
