Re: Attribute Syntax

[Daniel Merino <daniel.merino@unavarra.es>]

But I need to mix them. I need to search in the base "ou=People,..." and 
mix the attributes of the two bases, for searching i.e. all the Smith 
that are policemen or firemen, and get the attributes of the two bases.

That's why I need composed attributes, each one of that works have their 
own phone number and another possible atributes. (Police/911, Fire/555, etc)

Thanks anyway.
