[Bug 2042859] [NEW] [snap] Firefox snap cannot use kerberos authentication

[Sergei Genchev]

Public bug reported:

Applies to Ubuntu 22.04 and any other versions where firefox runs as snap:
firefox:
  Installed: 1:1snap1-0ubuntu2
  Candidate: 1:1snap1-0ubuntu2
  Version table:
 *** 1:1snap1-0ubuntu2 500
        500 http://us.archive.ubuntu.com/ubuntu jammy/main amd64 Packages
        100 /var/lib/dpkg/statu

 You can configure Firefox to use negotiate authentication with kerberos. https://people.redhat.com/mikeb/negotiate/ on how to do this.
 To use kerberos auth, Firefox needs to read kerberos ticket cache, default to /tmp/krb5cc_${id -u}. Since Firefox runs as a snap in 22.04, and possibly other versions, it cannot read this cache, and thus cannot use kerberized authentication. 
Firefox installed as native application works as expected.
