Hello...LDAP seems to crash.

Dear List,

    I have been encountering an issue with ldap giving the error:

DFCFFBEF51 1718 Thu Jul 18 11:44:55 gtegeder@pls-net.org pls-l@pls-net.org
 temporary failure. Command output: grpdeliver: ldap_search: No such 
object 

I have been working with SuSe to try and resolve the problem, however, I 
haven't made any progress.  I run SuSe Linux with E-mail Server III and 
it seems to work fine for the most part.  The main problem is that when 
a message is sent to a group of 150 people the error above is received 
and ldap and then the message is placed in the queue.   Once this 
happens the message is sent over and over again and never seems to leave 
the queue even after it's been delivered.  Does anyone have any 
suggestions?  Any help at all would be great even if it's only a place 
to read.  I can't seem to find why it's crashing.  The only idea I can 
think of is because it's 150 people maybe it's timing out when tryin to 
send.  But I don't see why the messages would make it through if that 
were the case.  Thank you in advance for any assistance you can offer. 
And if you need more specifics on the situation I can respond in detail.
