*
* Variables that come in as GET vars :
2009-06-30 09:29:51 +00:00
* - server_id ( handled in common . php )
2009-06-30 08:05:37 +00:00
* - search ( true if performing a search , empty to just draw form )
* For simple searches :
* - attribute , criterion , filter
* For advanced searches :
* - base_dn , scope , filter
2009-06-30 09:29:51 +00:00
*
* @ package phpLDAPadmin
* @ todo Search is probably broken , since base_dn is now an array
