The service stash file should contain:

cn=kdc-srv,cn=krbContainer,dc=example,dc=local#{HEX}...
cn=adm-srv,cn=krbContainer,dc=example,dc=local#{HEX}...

where the "..."s are the hex encoding of the supplied passwords.  In what way
is the file malformed?  libkdb5_util is able to read a password from it, or
you would see an error about reading the stash file instead of an error about
the LDAP server rejecting the credentials.  If I run the given commands, the
resulting file does not seem amiss.

(As an aside, the -D and -w options to these kdb5_ldap_util invocations should
be unnecessary, as this subcommand does not need to authenticate to the LDAP
server.)
