    Copy: kerberos@mit.edu (Jonathan Calmels via Kerberos)

    No; the names of these records are fixed by the standards. You can hand-configure the server names in krb5.conf instead of using DNS SRV
    records. However, even then, your Kerberos realm should not have the same
    name as a Windows domain -- that's essentially having two realms with the
    same name, which will not work out well.

    Hi to all,

    I'm having the following problem:

    I set up an openldap with kerberos, now I want to add the srv-records
    for Kerberos, but as DNS-Server we MUST use a DNS-Server from Active Directory. So I can't add a srv-record _kerberos._tcp, because the
    domain controller of the AD are keeping these records. So I would like
    to add my own srv-record like _olkerberos._tcp so that I can use these srv-records for krb5.conf. I'm already doing this for sssd, because
    there I can configure the name of the srv-record. Can I do the same in krb5.conf? If yes what do I have to do?

    Thanks

    Stefan

    You are barking up the wrong tree because your request also means you
    intend to use the same kerberos realm for two distinct realms, and this
    will not work and end up in pain.
    Get your own subdomain (or a completely different second level domain),
    and then you will be able to create your own records there.
