CIFS mount issue

[ddolecki108]

ON a FIPS hardeded system the RHEL support method to mount a CIFS share is to use sec=krb5, tried that, still getting errors:

[root@servername]# tail /var/log/messages
Jun 20 08:11:40 servername kernel: CIFS VFS: Send error in SessSetup = -126
Jun 20 08:11:40 servername kernel: CIFS VFS: cifs_mount failed w/return code = -126
Jun 20 08:11:40 servername kernel: CIFS VFS: Send error in SessSetup = -126

//share1 /mountpoint1 cifs sec=krb5,ro,credentials=/root/credentials 0 0
//share2 /mountpoint2 cifs sec=krb5,ro,credentials=/root/credentials 0 0

# rpm -qa | grep krb5

Did you join the client (that mounts the CIFS) to the AD/Identity Management?
