The theory for this sssd crash is that during rpm upgrading it,
sssd-2.8.2 gets installed, %post runs to restart it, but oh no,
sssd-ldap-2.7.4 is still in the system. sssd_be(-2.8.2) then falls
over its feet when it loads 2.7.4 .so files. Addin symvers like below
should prevent this and pin the modules to another: sssd_be's attempt
to dlopen libsss_ldap.so(-2.7.4) will fail because
libsss_ldap.so(-2.7.4) cannot find a libsss_util.so(-2.7.4), since
the system only has libsss_util.so(-2.8.2) at this point.
