[otrs] OTRS not automatically polling for new mail

Greetings, I believe that in trying to set up a Customer LDAP and Database data stores that OTRS may have gotten 'confused'. I pulled the offending configuration, and OTRS seemed to behave properly again, however, it is now not polling for new mails in my IMAP accounts. What may be the cause of this? How do I remedy this? Thanks,
