I assumed that using user=cifs, and having the keytab for user cifs in 
/etc/krb5.keytab would make it use the keytab entry.  In fact, I just 
tested it and it doesn't matter whether I put user=cifs in the autofs map, 
I don't see a user= in /proc/mounts.

# cat /proc/mounts |grep cifs
//fileserver/public/ /share/public cifs rw,relatime,sec=krb5,cache=loose,unc=\\fscluster\public,multiuser,uid=0,noforceuid,gid=0,noforcegid,addr=,unix,posixpaths,serverino,acl,noperm,rsize=1048576,wsize=65536,actimeo=1 0 0

and the autofs map:
   public | -fstype=cifs,sec=krb5,multiuser ://fileserver/public
