[krbdev.mit.edu #6345] no kdb5_util stash equivalent with LDAP database

[Russ Allbery <rra@stanford.edu> via RT]

This is Debian bug http://bugs.debian.org/484808

There appears to be no equivalent to the kdb5_util stash command for an
LDAP-only database.  kdb5_util stash doesn't work without access to a
traditional KDC database, and kdb5_ldap_util stashsrvpw does something
different.  This means that if one doesn't create a stash file during
the LDAP database creation with the -sf option, there isn't a good way
to create one later.
