Symptoms

Qmail related tasks fail in POA with the error message "Can't contact LDAP server" like in the example below:

Task name    Add mailname 'john' for domain 'customer.com', hosting #3
Task description    Add mailname 'john' for domain 'customer.com', hosting #3
Last execution output    LDAP returned error code -1, saying Can't contact LDAP server

Cause

The LDAP server used in Qmail hosting is down or unreachable from the POA Management Node.

Resolution

Check if the LDAP server is up and running.

  1. Log into POA Provider Control Panel

  2. Go to Service Director > Shared Hosting Manager > Qmail Services

  3. Find the IP address of the LDAP server(s) in the LDAP server address field

  4. Log into the LDAP server using SSH as root

  5. Check status of the LDAP service:

    # /etc/init.d/ldap status

  6. If you see that LDAP service is stopped - start it:

    # /etc/init.d/ldap start

Refer to the Odin Knowledgebase article if LDAP server cannot start due to corrupted database.

If the LDAP service is up and running check if POA can connect to the LDAP server:

  1. Log into POA Management Node (MN) using SSH or RDP

  2. Check connectivity from the POA MN to the port 389 of LDAP server using e.g. the telnet utility:

    telnet LDAP_SERVER_P 389

Replace LDAP_SERVER_IP in the command above with the actual IP address of the LDAP server which you found in the POA Provider Control Panel.

If the POA Management Node cannot connect to the port 389 of LDAP server then check firewall and routing settings in the network infrastructure.

In case slapd.log is absent - configure it, using this guide.
