Problem with demon sssd-pac after upgrade to 5.2.0

Hello!

After upgrading to 5.2.0 the daemon sssd-pac crashes after running a few hours. The demon itself can not be restarted, restarting sssd does not solve the problem. Only the reboot of the server activates sssd-pac. But only for a few hours, than it crashes again.

In the syslogs I found the info:
sssd_pac[1319361]: /usr/libexec/sssd/sssd_pac: error while loading shared librari
es: libndr.so.3: cannot open shared object file: No such file or directory

The package samb-libs contains the files libndr.so.[1|2|5] but no libndr.so.3.

Anyone an idea what could solve this problem?

Thanks in advance
