Dovecot differs between userdb and passdb.

It seems that passdb is running, but userdb is not.

How does your LDAP entry looks like? Should the user data be read from LDAP, BTW?

Does the LDAP filter mentioned in the logs return the results for the currently bound user, aka:

ldapsearch -D uid=wojtek,ou=Users,dc=frontline -W \

• -b ou=Users,dc=frontline
  '(&(objectClass=posixAccount)(uid=wojtek))' homeDirectory uidNumber

displays home and uid?

hi all, i cannot figure out how to solve my problem with dovecot+ldap configuration. please help...

i was reading through the emails from the list related to ldap. i added this debugging line 372: "i_info("LDAP: Received reply %d", msgid);" to src/auth/db-ldap.c. you can see part of my mail.info log file below.

most interesting is that actually if you give a wrong password to the email client program dovecot report it back. so it can verify this on LDAP. also you can see that one of the lines below say "client out: OK^I1^Iuser=wojtek". what looks to me as a successful authentication. and than it cannot find the user! what is strange, as when i execute a command line: "ldapsearch -h localhost -b 'ou=Users,dc=frontline' -D 'uid=wojtek,ou=Users,dc=frontline' -x -W" it works ok (see the result below in the quoted emails).

Steffen wrote that "userdb is not running" - i do not understand this. how do i make it run? i thought that both userdb and passdb are in LDAP. please see the structure of my LDAP record below in quoted email.

hi Steffen, i have to modify ldapsearch command you wrote and add '-x' switch for simple authentication instead of SASL. but otherwise the command display good results:

extended LDIF

LDAPv3

base <ou=Users,dc=frontline> with scope subtree

filter: (&(objectClass=posixAccount)(uid=wojtek))

requesting: homeDirectory uidNumber

wojtek, Users, frontline

dn: uid=wojtek,ou=Users,dc=frontline uidNumber: 30000 homeDirectory: /home/samba/wojtek

search result

search: 2 result: 0 Success

numResponses: 2

numEntries: 1

i am not sure how to show you the structure of the LDAP entry otherwise than just run a search without requesting specific field. here is the result:

wojtek, Users, frontline

dn: uid=wojtek,ou=Users,dc=frontline objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson objectClass: posixAccount objectClass: shadowAccount cn: wojtek sn: wojtek givenName: wojtek uid: wojtek uidNumber: 30000 gidNumber: 513 homeDirectory: /home/samba/wojtek loginShell: /bin/false gecos: Wojtek Bogusz userPassword:: [password here]
