It's not an issue I've encountered: I'm not using LDAP in my current 
workplace. But there are certainly more up-to-date kernels from 
Xensource available for DomU's. Can you use an RHEL 5 Dom0? I'm finding 
RHEL 5 Dom0's a good base on which to apply RHEL 4.5 and 5.0 guest 
domains, and a lot easier to support than RHEL 4 was as a Dom0.
I do use the Xensource free kernel on my RHEL 4.5 DomU, for network 
behavior reasons.
