Question: do you not have a actual OES-Server that hold the master eDir? and better two oes-server for a replica!

OES 24.3 is the actual version based on sles15sp4, oes24.4 is coming the next quartal

not all services / programs are validated for sles15sp6 and sles12sp5 is for me obsolete, but used as os for many ot-applications as zcm, zsd, filr, aa, etc...

this may be a wonder to had all on one os-version by ot, may be a dream from me!

No we don't use OES, just SLES

Why? What is the reason? i come from novell netware in 1985, had migrate to oes11 near 2010 and had migrated to all version, now on 24.3. It is very stable and any "more features" that sles not had.

Now i am retired and i continue to follow the development and participate on many beta products, i will not missed all this possiblities over a only sles-server!

It is not a critic, i ask for understanding other minds and experience!

great regards

I can think of a couple of reasons

- licenses

- security in depth: fewer services on a machine means smaller attack surface

- skills: you'd need someone who knows OES in addition to standard Linux knowledge

In many customer installations, there are SLES systems on which an eDir has been set up for precisely the reasons listed here. Outside I have large GroupWise installations running and in these systems I specifically go to a SLES/eDir for LDAP because very excessive LDAP requests can be handled better. Of course, this also applies to the other OT products that use LDAP. Other reasons are less workload, better security because there are fewer services and, above all, disaster recovery is much easier than with an OES system. Thanks for the valuable reminder of the reasons in the post

Thank you Norbert for the valuable reminders of the reasons too
