File symvers.patch of Package sssd

From 1ad3abee3ed69cad410aff5f2e17542d2f34deb7 Mon Sep 17 00:00:00 2001

Subject: [PATCH] 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.
