As above - it depends on the local security policy (addendum - and product
limitations). Password aging is not always acceptable to all organisations
(or subsets thereof). Encryption is great - if you can get multiple platforms
to read/use the same encrypted password field. :-)

Same here - but for the moment we're stuck with the U.S. export restrictions
hampering development of this. I'd like to see something in OpenLDAP's
ultimately LDAPv3 support (so that we don't have to go with Kerberos
everywhere) - I'm told something is under development, but we'll just have to
wait and see. SSLv3/TLSv1? GSSAPI? Who knows..

Why? It's not a "problem" it's a "design decision" - one that may actually
match perfectly with the security policy in some organisations. Not all
systems need (or want) to send passwords over a network (encrypted or
otherwise). If that's the case, then the whole "system" needs to ensure that
passwords don't "leak" anywhere (thus taking us back to the original question
of why you wouldn't want someone to see their own password field).
