kadmin bug (missing mod_name)

["Jacques A. Vidrine" <n@nectar.com>]

Hello,

kadmin will crash when you `get' a principal, and that principal entry
does not have a modifier associated with it (i.e. mod_name == NULL).
This is the case when using the Heimdal KDC with an LDAP backend.
The following patch should be used to save sanity:

Why the LDAP hdb has problems finding a modifier is another story I
haven't determined yet.
