How to add a datafield proxyauth ?

[Holger Banko <holger.banko@pgam.com>]

Hi,

I want to add a datafield proxyauth for squid password authentication to my 
LDAP-Tree. How can I make it and whats the best way ?

Create a new schema or add it to an schema that I already use (core, 
inetorgperson) ?
