Shared Services LDAP issue... Error Instantiating 'dc=EPMSystem': null

Question

I entered a new LDAP connection in Shared Services (evidently incorrectly) and even thought it verified when entering the data I can't get the environment back up.. So, without being able to login to SS how am I supposed to make changes to the LDAP settings to correct it??
Is there a way to reset the LDAP information in SS to some type of default?
I could really use a hand with this one.. any thoughts or suggestions are welcomed.
Thanks,

Thanks John as always for your responses.
I logged an SR with ORACLE 3 days ago and am still waiting for a response.. I will say however it was logged as a non-emergency since this is a DEV environment. I'm hopeful that there is a documented solution for restoring the LDAP somewhere in their technical notes.
All the solutions I tried were based on an LDAP restoration from a backup since deleting the LDAP folder(s) results in a total LDAP restoration which I wasn't interested in so I avoided that path.
I tried renaming the LDAP folder in each application and restoring the LDAP in Foundation I was assuming the other apps would get updated from Foundation but that didn't work... not sure why but it didn't.
I ultimately was able to get the environment back up by essentially by restoring the LDAP from one of the backups stored in '/oracle/Middleware/user_projects/domains/EPMSystem/servers/FoundationServices0/data/ldap/backup'. I'm not 100% certain on how the communication flows between the different applications installed in the suite and I tried a number of things before landing on just restoring the Foundation LDAP and then sequentially starting the other applications, it seemed to work.
