Hi there!
I'm using the package krb5-kdc-ldap to use mi kerberos with LDAP backend.
I've followed the debian and ubuntu documentation and I find some
issues I can't solve:
· I fill the LDAP tree using the "kdb5_ldap_util" as seen in
documentation. The LDAP server is correctly written.
· The stash are created, with the neccesary credentials.
· When initializing the admin interface, with kadmin.local, i get:
kadmind[26023](Error): Can not fetch master key (error: Cannot
find/read stored master key). while initializing, aborting
The same when starting the service in /etc/init.d. In both cases, the
LDAP server is strongly readed:
krb5kdc: Can not fetch master key (error: Cannot find/read stored
master key). - while fetching master key K/M for realm EXAMPLE.ES
So, I think the options are:
1) In the LDAP server some information is missing (a bug in kdb5_ldap_util?)
2) There is something I don't understand in the procedure.
My config is:

kadmin.local debug (strace). In pastebin because there are a lot of lines:

Any idea?
Best regards.
