Hi,

many new features rely on library APIs and features that are only available in recent versions of SSSD dependencies. As a result, the code often needs #ifdefs and special branches in order to at least compile or run on RHEL5.

So far we've been doing nightly builds also for RHEL5 and fixing issues as we were finding them. But recently we are considering dropping support for RHEL5 -- it is causing some engineering effort and at the same time the audience is probably very limited. If you are running super-stable enterprise distribution, chances are you are not all that interested in the latest and possibly very unstable SSSD version.

The proposal would be to keep building and supporting the 1.9.x branch for RHEL5 and switch to using RHEL6 as the oldest supported release starting from the 1.10 upstream version. Of course we would still accept patches from any potential contributors.

Any objections against the plan?

I'm about to discontinue RHEL5 builds of master/1.10 unless there is an objection.

The recent changes in the 1.10/master branch make it harder and harder to support such an old platform without substatial effort and I don't really think there are many users of bleeding edge SSSD on a stable platform.

If there are no objections I will shut down the RHEL5 nightly builds of the master branch tomorrow.

Our current nightly builder doesn't support building from different branches for different "targets", so in order to build sssd-1-9 nightlies for RHEL5, I'd have to set up another repo. Is anyone interested in running sssd-1-9 on RHEL5? If so, then I could set up a new repo, probably on repos.fedorapeople.org or someplace similar.

I understand that you want to get rid of the additional effort.

Would you be still willing to accept a feature request for 1.9.x? I'd like to use LDAP SASL/EXTERNAL bind with SSL client certs.

My customer is definitely stuck to still using RHEL5 for a while but we plan to use 1.9.5+ on that platform.

Ciao, Mcihael.

This is currently planned for 1.11 upstream: https://fedorahosted.org/sssd/ticket/561

Although the shape of 1.11 and 1.12 might change in the nearest future. When the ticket is implemented for master, we can consider backporting it to 1.9.x, sure.

But it's definitely not going to make 1.10, if you need this support sooner, patches would be mostly welcome. (Or contact your RH support representative to escalete this RFE).

OK, seems like there is a number of people interested in running 1.9.x on RHEL5, so I'm going to set up a repo with 1.9.x nightlies on repos.fedorapeople.org.

It turned out that the friendly people running out builder were able to hack the Makefiles and switch the el5 repo to building from the 1.9.x branch. (Thanks Nalin and John!)

To sum it up: SSSD has *dropped* support for RHEL5 in the master branch that will become upstream 1.10. The RHEL5 nighlies are now being built from the 1.9.x branch and will continue in the foreseeable future.

Thanks again for the feedback.
