Bug 212145

Use podman to create two pod. One work as samba server. One work as client. Setup samba and kerberos in server. Then mount cifs in client. It's failed. But if execute kinit in host. Then mount successfully.


In container client:
[root@849a34460dc9 /]# uname -r
5.12.0-rc1+
[root@849a34460dc9 /]# kinit root
Password for root@RHQE.COM: 
[root@849a34460dc9 /]#
[root@849a34460dc9 /]# mount //b3472c982938/share1 -overs=3.11,sec=krb5 /mnt/cifsmp
mount error(126): Required key not available
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

Then login into host and execute kinit

Host:
[root@kvm-04-guest06 ~]# kinit root
Password for root@RHQE.COM:
[root@kvm-04-guest06 ~]#

Back to container client:

[root@849a34460dc9 /]# mount //b3472c982938/share1 -overs=3.11,sec=krb5 /mnt/cifsmp
[root@849a34460dc9 /]#
