Environment

iPrint on Open Enterprise Server
iPrint 3.x appliances
 

Situation

Print manager can be managed via iManager, but the printers are not seen in the IPP page.

When accessing the IPP page, the following error is displayed: DataModelException: Failed : HTTP error code : 500 when trying to see printers in iPP page.

When checking LUM with a namconfig -k, an error states that the ldap server cannot be contacted.

A server restart after renewing the certificates does not resolve the issues.
 

Cause

The SSL certificates has just been renewed with external certificates, which are valid, but not properly linked to eDirectory, LDAP and LUM.
 

Resolution

1. Edit /etc/opt/novell/iprint/httpd/conf/iprint_ssl.conf and verify or change the line from the DNS name to the IP address of the iPrint manager server:

FROM AuthLDAPDNURL "ldaps://vce-kcg.kcg.local:636/???(objectClass=user)"

TO AuthLDAPDNURL "ldaps://10.10.1.2:636/???(objectClass=user)"

2. The following series of commands is to link/repair the external certificates into eDirectory.
From a terminal or putty session. type the command below and press enter:
 

#rcndsd restart;chmod 775 /opt/novell/iprintmobile/bin/certman.sh;/opt/novell/iprintmobile/bin/certman.sh -t edir -r;rcapache2 restart;rcnovell-iprint-mobile restart;rcnovell-ipsmd restart

3. Type the following command to make sure that the external certificates are associated for use with LDAP:
 

#namconfig -k

4. Type the following to clear the namcd cache:
 

#namconfig cache_refresh

5. Restart services by typing the following commands:
 

#rcapache2 restart
#rcnamcd restart
#rcnovell-ipsmd restart

6. Try logging into the iPrint manager again. By doing so, the errors should be resolved, and be able to successfully manage the iPrint manager and printers.
