Password issues

I’m running an OS 10.3.4 Open Directory server for authentication on Windows, OS X and Linux. Works great, no compliants. The problem now is that we need to add IRIX clients to the mix. After working with SGI tech support for two weeks now I have come down to the decision that when attempting to access the LDAP server with SGI’s addmittedly bad implementation of LDAP, the passwords that *should* be sent as an encyrypted string (ie: {CRYPT}*password string*) is being sent as a string of asterisks. I’ve tried for weeks to configure it other wise, for both anonymous and authenticated binding, but no matter what I do, the IRIX servers are always receiving a string of asterisks. So basically my question is, does anyone know if it is the case that Apple’s LDAP does not send the encrypted password string? and if so, does anyone know how to get around this?
