Description Julian Ospald 2015-09-20 16:20:34 UTC
http://www.openldap.org/its/index.cgi/Incoming?id=7978 suggests that lanman hash support is insecure

Howard Chu (the chief architect of OpenLDAP) said:

And it appears it will be gone in 2.5 anyway.

In our ebuild, "lmpasswd" is behind the samba USE flag. For whatever reason.

I doubt we need it anymore, but I don't know if I feel comfortable removing it, robbat?

If it's gone in openldap-2.5, we'll drop it then. It's behind the USE=samba, because that was the only place that used it.

If our supported versions of samba no longer use it, then we can drop it; note that Samba 4.3 still supports it as well, for inter-operation with old systems.

I agree that nobody should be using it anymore, since it's insecure; but I'm not going to break old use cases. I know amongst them is a Samba-on-IRIX deployment I did over a decade ago, which still has some systems going.
