LDAP attribute mapping

[Arran Cudbard-Bell]

Quick poll.

For 3.0 the ldap module will be moving away from using the ldap.attrmap file and instead use a config based mapping.

There are a few ways we are considering for organising the mapping.

We can use something like the existing unlang:

update control {
	Cleartext-Password := userpassword
}

update reply {
	User-Name = radiusUserName
}

update outer.reply {
	Reply-Message = radiusReplyMessage
}

Or something like rlm_rest  and rlm_cache:

update {
	control:Cleartext-Password := userpassword
	reply:User-Name = radiusUserName
	reply.outer:User-Name = radiusUserName
}

It really depends on whether people are actually using the full ldap.attrmap, or whether they're just pulling out one or two attributes. Each approach is as efficient as the other performance wise, so it comes down to which one people prefer.

Any thoughts?
