6.14 OpenLDAP on OES 2
You cannot run OpenLDAP on an OES 2 server with eDirectory installed. eDirectory LDAP is
required for OES 2 services and uses the same ports as OpenLDAP.
6.15 Samba
For Samba implementation caveats, see
Guide.
6.16 Virtualization Issues
The following are caveats for setting up OES 2 server in Xen VMs:
Section 6.16.1, "Always Close Virtual Machine Manager When Not in Use," on page 71
Section 6.16.2, "Always Use Timesync Rather Than NTP," on page 71
Section 6.16.3, "Backing Up a Xen Virtual Machine," on page 71
Section 6.16.4, "Time Synchronization and Virtualized OES 2," on page 71
Section 6.16.5, "NSS Considerations," on page 72
6.16.1 Always Close Virtual Machine Manager When Not in Use
You should always close Virtual Machine Manager (VMM) when you are not actively using it.
Virtual Machines are not affected.
Leaving VMM open can affect the system resources available to the VMs.
6.16.2 Always Use Timesync Rather Than NTP
Time synchronization problems have been observed when virtualized NetWare servers are running
the XNTPD NLM
. Therefore, Novell strongly recommends using Timesync and also configuring
TM
the service to communicate through NTP.
6.16.3 Backing Up a Xen Virtual Machine
When backing up a Xen virtual machine running virtualized NetWare, we recommend using a
remote backup source rather than a local tape device because of limitations in detecting a local tape
device.
6.16.4 Time Synchronization and Virtualized OES 2
eDirectory relies on time being synchronized and connections with eDirectory are lost if the system
time varies in the host operating system. Be sure you understand and follow the instructions in
Virtual Machine Clock Settings (http://www.novell.com/documentation/sles10/
book_virtualization_xen/data/sec_guest_suse.html#sec_xen_time)
Settings" (http://www.novell.com/documentation/sles10/book_virtualization_xen/data/
