Package: krb5-doc
Severity: normal

Hi,

I have not actually setup the necessary environment to reproduce this
bug on Debian, but I have (tried to) examine the source code and
believe the bug exists in Debian.  I do know that this bug exists on
Ubuntu, and have examined the Ubuntu-specific patches and found
nothing that I can see affects the bug.

Here is a copy of the Ubuntu bug report:

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.


The Ubuntu bug can be found at:
https://bugs.launchpad.net/ubuntu/+source/krb5/+bug/2012140

Above /tmp/krb5cc_127408622_wH2NwY cached credential file produced by
an MS Active Directory user login.

(This bug also makes username= cifs mounts fail.)

Apologies if this bug report is nothing but noise.  But I'd like to
get the attention of somebody, so cifs/smb3 per-user mounts don't take
gobs of research.  I will file a related cifs-utils bug and update this
bug with the bug number.  I'm hoping that a "kerberos person" can easily
verify the issue and so I'm not wasting too much of your time.

Thanks.
