Capitalization question

[Kanevsky_Arkady@emc.com]

Can I use capitalization in names used in kerberos domain?
I am bumping into a issue when capital letters are used in domain but not in the hostname only.
Details below.
Needless to say all sort of other authentication also fails.


[root at nf-ArkTEST-sto ~]# hostname
nf-ArkTEST-sto.ArkTEST.name.company.com

>From listprincs:
host/nf-ArkTEST-sto.ArkTEST.name.company.com at ARKTEST.NAME.COMPANY.COM

nfs/nf-ArkTEST-sto.ArkTEST.name.company.com at ARKTEST.NAME.COMPANY.COM


[root at nf-ArkTEST-sto ~]# ktutil
ktutil:  rkt /etc/krb5.keytab
ktutil:  l
