RE: OpenLDAP, Heimdal, kpasswd crash (ITS#2386)

This is a bug in Heimdal, the Heimdal library is dereferencing a NULL pointer
because it didn't first check to see if the pointer was valid. I suggest you
report this bug to the Heimdal maintainers.

Use of this Kerberos passwd feature is discouraged; your clients should use
SASL/GSSAPI instead. Using the Kerberos password in this manner exposes it on
the network, which completely violates the Kerberos security model. No one
should ever use this feature.
