dovecot - Aug 2004 - dovecot+postifx+ldap

hi,

i'm trying to set a dovecot/pop + postfix couple with ldap authentification.
and i'v got a lots of troubles.

hers's my dovecot.conf

protocols =  pop3
login = imap
login = pop3
first_valid_gid = 1000
last_valid_gid = 0
mail_extra_groups = mail
default_mail_env = maildir:/var/mail/%1u/%u/Maildir
mbox_locks = dotlock flock
auth = default
auth_mechanisms = plain
auth_userdb = ldap /etc/dovecot-ldap.conf
auth_passdb = ldap /etc/dovecot-ldap.conf
auth_verbose = yes


here's dovecot-ldap.conf

hosts = 192.168.128.1
dn = cn=manager,o=dental-on-line
dnpass = dolmaster
ldap_version = 3
base = ou=002f83,ou=machines,ou=fr,o=dental-on-line
deref = never
scope = subtree
user_attrs = uid
user_filter = (&(objectClass=posixAccount)(uid=%u))
pass_attrs = uid,userPassword
pass_filter = (&(objectClass=posixAccount)(uid=%u))
default_pass_scheme = PLAIN
user_global_uid = 1000
user_global_gid = 1000

and, a ldif exempl:

dn: uid=mwerly, ou=002F83, ou=machines, ou=fr, o=dental-on-line
displayName: WERLY Marc
shadowExpire: -1
mobile: 000
objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: inetOrgPerson
objectClass: posixAccount
objectClass: shadowAccount
userPassword:: eHh4
shadowLastChange: 10000
facsimileTelephoneNumber: 01.43.21.54.75
uid: mwerly
uidNumber: 12164
cn: Marc WERLY
shadowInactive: -1
loginShell: /bin/bash
shadowMin: 0
gidNumber: 100
shadowMax: 999999
gecos: mwerly
homeDirectory: /home/mwerly
sn: Marc
shadowWarning: 99

1 it seems unable to authenticate with
pop3-login: Login: mwerly [192.168.1.7]
Aug 31 17:47:35 dental01 pop3: I/O leak: 0x8050d70 (0)
Aug 31 17:47:35 dental01 pop3: I/O leak: 0x8084db0 (1)

:o(
2 if I comment
user_global_uid = 1000
user_global_gid = 1000
dovecot can't get uidnumber from ldap, in spite of its presence in ldap 
entry :'o(

3 postfix seem able to send messages to local virtual users(thanks of 
ldap/pam ldap authentification). the /var/mail/%u files are up2dated by 
postfix, but I simply can't get any mails with thoses dovcot logs:
pop3-login: Login: mwerly [192.168.1.7]

You have to specify in your user_attrs which parameters give the 
uidnomber and the gidnumber in your ldap directory:

# User attributes in order:
#  Virtual user name (user at domain)
#  Home directory
#  MAIL environment
#  System user name (for getting user's groups from /etc/group)
#    - For virtual users you don't want to use this, so this defaults to 
none.
#  System UID
#  System GID
#user_attrs = uid,homeDirectory,,,uidNumber,gidNumber

ok, thanks, it gets uidnumber. but, what does mean thoses I/O leak??? is 
  it some kind of internal errors???dovecot can't authenticate any way

Looks like the only way for those I/O leaks to happen is if user is 
authenticated ok, but mailbox can't be opened for some reason. I fixed 
this now and also made it always log at least some error message. The 
I/O leaks themselves are just warnings that everything wasn't cleaned 
up properly.

Your real problem is probably that the pop3 user don't have permissions 
to the mailbox or it doesn't exist.

the /var/mail/%u files exist, and I put 777 mask. but, i can't read my 
mails, even when i'm authentified. how to allow mbox with dovecot???

my setup doesn't make any thing

default_mail_env = mbox:/var/mail/%u
