[Bug 1241167] [NEW] Case sensitive principle names

[StuartIanNaylor]

Public bug reported:

https://help.ubuntu.com/community/Kerberos

"Principals
Principals are entries in the Kerberos database that represent users or services on the network. Each user or service that is participates in a Kerberos authentication realm must have a principal defined in the Kerberos database.

User principals take the form principal at REALM.NAME. For instance, user
tom on the EXAMPLE.COM realm should have a principal tom at EXAMPLE.COM in
the Kerberos database.

Service principals take the form service/server.fqdn at REALM.NAME. For
example, the FTP service on lab.example.com in the EXAMPLE.COM realm
would have the principal ftp/lab.example.com at EXAMPLE.COM in the Kerberos
database.

Principal names are case sensitive."

This one is a bit chicken and egg.

It would seem windows 7 returns principle names in the form
host.DOMAIN at DOMAIN

whilst the ubuntu implementaion is host.domain at DOMAIN

with kerb being case sensitive its brings the question who is right or
what is the fix?
