* Perform LDAP searches and draw the advanced/simple search forms
*
* Variables that come in as GET vars:
* - 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
2009-06-30 10:46:00 +00:00
* @todo Order doesnt Order properly - probably case related.
