Re: ldapsearch equivalent with Net::LDAP

My previous (albeit limited) attempts to debug dlap calls in perl have  
been facilitated by:
1) pulling down a copy of the ldif file.
2) phpldapbrowser.php

Not all ldif files are made the same... custom fields and non-standard  
field content can sometimes make it look like your code is wrong when,  
in fact, it's doing exactly what you thought it should.

YMMV.
