Hi folks.
New to both dovecot and openldap. Trying to set up virtual domains using the wanderingbarque howto:
http://www.wanderingbarque.com/mailserver.html
Platform is RH enterprise 3.
Only difference is I'm trying to use phamm instead of jamm:
dovecot doesn't seem to want to play nice with my openldap; everything else (postfix, etc) seems to work alright. So I'm looking for some hints as to what I'm doing wrong. thanks in advance!
When I do an /sbin/service dovecot restart, here's the error from /var/log/ldap.log:
<snip> Dec 11 13:59:22 salcha slapd[15734]: => access_allowed: auth access to "cn=dovecot,dc=akforecast" "u serPassword" requested Dec 11 13:59:22 salcha slapd[15734]: => dnpat: [1] .*,jvd=([^,]+),o=hosting,dc=akforecast nsub: 1 Dec 11 13:59:22 salcha slapd[15734]: => dnpat: [2] .*,jvd=([^,]+),o=hosting,dc=akforecast nsub: 1 Dec 11 13:59:22 salcha slapd[15734]: => dnpat: [3] .*,jvd=([^,]+),o=hosting,dc=akforecast nsub: 1 Dec 11 13:59:22 salcha slapd[15734]: => dnpat: [4] o=hosting,dc=akforecast nsub: 0 Dec 11 13:59:22 salcha slapd[15734]: => acl_get: [5] check attr userPassword Dec 11 13:59:22 salcha slapd[15734]: <= acl_get: [5] acl cn=dovecot,dc=akforecast attr: userPassword Dec 11 13:59:22 salcha slapd[15734]: => acl_mask: access to entry "cn=dovecot,dc=akforecast", attr " userPassword" requested Dec 11 13:59:22 salcha slapd[15734]: => acl_mask: to all values by "", (=n) Dec 11 13:59:22 salcha slapd[15734]: <= check a_dn_pat: * Dec 11 13:59:22 salcha slapd[15734]: <= acl_mask: [1] applying none (=n) (stop) Dec 11 13:59:22 salcha slapd[15734]: <= acl_mask: [1] mask: none (=n) Dec 11 13:59:22 salcha slapd[15734]: => access_allowed: auth access denied by none (=n)
Anyone see any big,glaring 'yewidiut' errors? Or just hints as to what could be wrong?

Normally you should leave this alone, unless you know # what most of your IMAP clients are.

## ## Authentication processes ##
# An Authentication process is a child process used by Dovecot that # handles the authentication steps. The steps cover an authentication # mechanism (auth_mechanisms, how the client authenticates in the IMAP or # POP3 protocol), which password database should be queried (auth_passdb), # and which user database should be queried (auth_userdb, to obtain # UID, GID, and location of the user's mailbox/home directory). # # You can have multiple processes, though a typical configuration will # have only one. Each time "auth = xx" is seen, a new process # definition is started. The point of multiple processes is to be able # to set stricter permissions. (See auth_user below.) # # Just remember that only one Authentication process is asked for the # password, so you can't have different passwords accessible through # different process definitions (unless they have different # auth_mechanisms, and you're ok with having different password for # each mechanisms).
