Looks like an authentication failure:

[25/Jan/2011:15:11:29 -0500] conn=391 op=0 BIND 
dn="uid=kdc,cn=sysaccounts,cn=etc,dc=domain,dc=com" method=128 version=3
[25/Jan/2011:15:11:29 -0500] conn=391 op=0 RESULT err=49 tag=97 
nentries=0 etime=0
[25/Jan/2011:15:11:29 -0500] conn=391 op=-1 fd=73 closed - B1

The ldappwd file on both systems look identical. I don't think that the 
SSL certificate comes into the equation, but I have no way of knowing 
whether it initiates TLS or not.
