You need to rebuild sssd against libldb required by the newer samba
(4.7). This was discussed >extensively on the list right before 4.7 RC1 release.
Do you know if more recent RHEL7 (1.15 in RHEL7.4 e.g.) addressed the
libldb incompatibility (and resultant sssd crash) that Alexander
noted? The version of sssd in RHEL7.5 beta didn't appear any newer
(but is there a RHEL7.x build of 1.16 we could try)?

New subject: sssd crash on RHEL 7.3
I am expecting that RHEL7.5 still has problems with Samba and SSSD library problems e.g. I
see this comment indicating that RHEL 7.5 beta sssd (even with default Samba in RHEL) is
broken https://github.com/cockpit-project/cockpit/issues/7916
The crash is in a similar location (memberof.so+1000):
-- Unit sssd.service has begun starting up.

There is no RHEL 7.5 beta
available yet.
At any given release, samba+libldb in that release is consistent. The
problem only occurs if you are intentionally building Samba (or libldb)
version which is incompatible with what is in the platform.
Since you want to build Samba git master and that one requires libldb
1.3, anything built against 1.2.2 is not compatible with libldb 1.3.
That's the problem.
This means if you truly want to get libldb 1.3 and git master of Samba
on your system, you need to rebuild SSSD yourself.
For development purposes we use COPR repositories for this. This is
what, for example, freeIPA team is doing.

At any given release, samba+libldb in that release is consistent. The
problem only occurs if you are intentionally building Samba (or libldb)
version which is incompatible with what is in the platform.
Since you want to build Samba git master and that one requires libldb
1.3, anything built against 1.2.2 is not compatible with libldb 1.3.
That's the problem.
This means if you truly want to get libldb 1.3 and git master of Samba
on your system, you need to rebuild SSSD yourself.
Just a small correction.
libldb-1.2.2 and libldb-1.3.0 works well with sssd and does not require
any rebuild of sssd.
From SSSD Point of view, there is just a problem with older or newer
version than libldb-1.1.30.
And it was solved in fedora on rpm level to check that and prevent
crashes
fedora <= 26:
* has libldb-1.1.29
* conflict in sssd spec file
https://src.fedoraproject.org/rpms/sssd/blob/f26/f/sssd.spec#_254
fedora >= 27
* has libldb 1.2.2 (1.3.0 in updates-testing)
* sssd requires libldb >= 1.2

Thanks, Lukas. I
forgot that the split was at 1.1.30.
