Hi list,

I have noticed that there is a slight difference in host principals when 
joining to AD using "net" command or via "adcli/realm".
All commands generates the short version (i.e. as per "hostname -s") in capital 
letters in AD, but in local kerberos keytab, the "net" command generates all 
"host/" principals lower case, but "adcli" generates then upper case - which 
renders kerberized access via ssh unusable in case we specify hostname without 
the domain suffix:
# cat /etc/hostname
Myshostname

Question, why do you convert the short hostname to uppercase? Why is sshd so 
picky about lower/upper cases for the host principals in Kerberos keytab?
Thanks,

Ondrej
