Title:
  The documented DEFCCNAME is not the actual credential cache name

Status in krb5 package in Ubuntu:
  New
Status in krb5 package in Debian:
  Unknown

Bug description:
  The krb5 documentation says that DEFCCNAME is /tmp/krb5cc_%{uid}.  But
  actual credential cache file names look like:
  /tmp/krb5cc_127408622_wH2NwY

  Setting [libdefaults] default_ccache_name to krb5cc_%{uid} in
  /etc/krb5.conf produces the expected credential cache file.

  Unless you know this, using "mutiuser" in fstab with cifs/samba/smb
  mounts is nigh impossible.
