My iprint server just stop printing this afternoon. 

When I try to connect to the iprint appliance configuration/printers, it gives me an RPC communication error just like in this document  Knowledge Document: iPrint Printers Configuration fails with RPC Communication Error

I tried to renewed the LDAP certificate with the following command.

rcndsd restart;sh /opt/novell/iprintmobile/bin/certman.sh -t edir -r

I get the following output

Note: SysVinit eDirectory system is not recommended on this platform. Refer to documentation for eDirectory usage on this platform
Generating eDir certificates
ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)
Deleting existing certificates
Creating new certificates
Note: SysVinit eDirectory system is not recommended on this platform. Refer to documentation for eDirectory usage on this platform

the LDAP certificate is back but still can't print.  When I try to shutdown a printer using the iManager iPrint control, I getting 
Exception printer control 

The only snapshot I have of this server is back in January, I'm not sure if that's going to cause any problems if I revert to this.

We use iPrint with Papercut 

We are still on iPrint appliance 4.2.8
