[Samba] Openldap for PDC

[Philip Washington]

I have been testing with openldap_2.2.13-2  and have experience on 2 
occasions lockups where the ldap server does not respond (slapcat will 
just hang).  I have upgraded to openldap_2.2.13-4.
Is there a recommended version of openldap for SambaPDC?
Does anyone have a system in production using openldap_2.2.13-2 or 
openldap_2.2.13-4?
I'm currently using samba3-20b  any recommendations for a production 
system would be welcome.
