[SSSD-users] auto-discovering sssd domains in upper case? (one small nit)...

[Spike White]

All,

When I was first crafting my sssd.conf file, I very much attempted to make
all my sssd domains upper-case.  Because in my (naive) view, an AD domain
is just a Kerberos realm (+ LDAP + nice admin screens).

As you know, Kerberos is very much case-sensitive.  (Technically, AD is
not.  but the convention in the /etc/krb5.conf file is to always put
Kerberos realms in upper case).

Back to sssd.

When sssd auto-discovered the other parent and child domains, it discovered
them in lower case.  I was left with a mix of upper and lower-case sssd
domains.  Even worse, the one local AD domain showed up twice.  Once in
upper-case (explicitly defined in sssd.conf) and once in lower-case
(auto-discovered).

Eventually, I gave up and went with the (apparently recommended sssd)
convention of lower-case sssd domain names.  In the domain definition, I
list the krb5_realm in upper case:

   [domain/amer.example.com]
   ...
   krb5_realm = AMER.EXAMPLE.COM

This is extremely unimportant (lower case works).  But is there an option
to auto-discover sssd domains in upper case?
