linux md5 password --> openldap?

["Graeme Joyce" <openldap-list@jade.co.nz>]

In Linux /etc/shadow we have passwords that look like:

$1$KhnoybOU$E80qNnpDUEZDCNU5wP9j41

I believe this is some form of MD5 password. I'd like to be able to copy
this into OpenLdap so the user can bind to ldap with their linux password.
Have tried various things like {md5}E80qNnpDUEZDCNU5wP9j41 but no luck so
I'm obviously missing the point.

Does anyone know what the details of this password format are, and if I can
somehow turn it into an md5 password that openldap will understand?

btw I can generate and use md5 passwords with ldappasswd no problem.

Thanks
Graeme
