Slow LDAP Authetication in 10.5.

We are currently using 10.4.11 to authenticate to our 10.3.9 LDAP server. Log in takes about 20 seconds. When we test out a 10.5 machine to the same server it takes 2 minutes. Here's a clipping from the LDAP log, maybe someone will see something in that. I am trying to log in as user p194xxx.
