The order is important. The first name listed is the "proper name" of
the attribute and the second and any other names listed are the aliases.

It won't matter to the OpenLDAP server, but if you're using something
like GQ, or Net::LDAP you will get yourself in trouble. Neither of
those client side tools understand/follow aliases. I've gotten myself
into quite some trouble during my development phase by referencing the
alias for an attribute in my PERL code and winding up trying to add a
duplicate attribute because my PERL code didn't know that "fax" was
really "facsimiletelephonenumber" for example. I've also found that GQ
0.6.0 has the same problem -- so I have take to the practice of using
the real names for attributes in my objectclass definitions.
