Description Manu Augustine 2017-08-10 12:18:41 EDT
Description of problem:

It appears that SSSD service is unable to start on a rhel 7.3 client after it was updated with latest security updates

Version-Release number of selected component (if applicable):
sssd, /usr/bin/net

How reproducible:


Steps to Reproduce:

1. Apply only security updates,
   [root@rhel7u3-2 rhn]# yum update-minimal --security
2. Try to join to a domain using realm command
   [root@rhel7u3-2 rhn]# realm join gsslab.pnq.redhat.com -v
     * Resolving: _ldap._tcp.gsslab.pnq.redhat.com
     * Successfully discovered: gsslab.pnq.redhat.com
     Password for Administrator: 
     /usr/bin/net: relocation error: /usr/lib64/samba/libgse-samba4.so: symbol  krb5_get_init_creds_opt_set_pac_request, version krb5_3_MIT not defined in file libkrb5.so.3 with link time reference
 ! Joining the domain gsslab.pnq.redhat.com failed
realm: Couldn't join realm: Joining the domain gsslab.pnq.redhat.com failed


3.

Actual results:
     /usr/bin/net: relocation error: /usr/lib64/samba/libgse-samba4.so: symbol  krb5_get_init_creds_opt_set_pac_request, version krb5_3_MIT not defined in file libkrb5.so.3 with link time reference
 ! Joining the domain gsslab.pnq.redhat.com failed
realm: Couldn't join realm: Joining the domain gsslab.pnq.redhat.com failed

Expected results:
Join should be successful

Additional info:

Issue will be resolved if I update krb5-libs package to the latest version (1.15.1-8.el7)
Comment 5 Andreas Schneider 2017-08-11 02:54:26 EDT
This sounds like that there is a krb5 update the customer didn't install?
Comment 7 Andreas Schneider 2017-08-11 09:11:58 EDT
So does it work if you update krb5?
Comment 16 Lukas Slebodnik 2017-08-14 15:16:03 EDT
Andreas,
I think you would need to add explicit requires to newer krb5 in samba-client-libs. (+ other packages which use newer krb5 symbols).

IMHO it can be part of next Z-stream update for another bug or security update.
Because there is simple workaround.

Sanity Only.
