Topic: authentication problem

Hi Guys,

I am running into authentication problem.

Every one of my users are asked to enter the password when they are connecting to the mail server from their email client.

From var/log/maillog i found this..


fatal: proxy:ldap:/etc/postfix/ldap_virtual_alias_maps.cf(0,lock|fold_fix): table lookup problem
Jan 28 23:33:31 123.456.789.0 postfix/proxymap[20935]: warning: dict_ldap_connect: Unable to bind to server ldap://127.0.0.1:389 as cn=vmail,dc=projectsjunction,dc=com: -1 (Can't contact LDAP server)

Did you try to recovery LDAP data? It should work as openldap complains this.

Re: authentication problem

I fixed it by running     slapd_db_recover -v -h /var/lib/ldap/


make sure to include your domain name if any after /var/lib/ldap/..

and the owner/group of /var/lib/ldap should be ldap with 700
