Slackware: mount cifs with kerberos

On Slackware14.0

Compiled cifs-utils with kerberos support
on request-key.conf added

create  cifs.spnego     *       *               /usr/sbin/cifs.upcall %k %d

But when i try

 mount -o sec=krb5 -t cifs //SLACK64//Users  /media/users
mount error(38): Function not implemented
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

On dmesg

[ 5179.071706] CIFS VFS: Kerberos negotiated but upcall support disabled!
[ 5179.071713] CIFS VFS: Send error in SessSetup = -38
[ 5179.071791] CIFS VFS: cifs_mount failed w/return code = -38

Any help?Thanks

Ops!

"# CONFIG_CIFS_UPCALL is not set"

:eek:

Need to recompile kernel
