Mountig cifs share using kerberos

Hi,

I'm trying to mount CIFS shares using Kerberos with Centrify Express.

I've read all the posts I could find here about it, but it keeps failing.

What I do, I use the keymap cache file of the user krb5cc_<uid>, change the file ownership to root, and type:

KRB5CCNAME=/tmp/krb5cc_<uid> mount -t cifs -o sec=krb5i,user=<user> //server/share /mnt

I get error message:

mount error(524): Unknown error 524

My linux is Ubuntu 14.04, Centrivy Suite version is 2016.1 and adbindproxy version is 5.3.0.

Any idea?
