[turba] Size limit exceeded warning?

[John Dalbec]

The version of Turba that I have installed (RELENG CVS from around 
March) doesn't issue a warning message if I run an LDAP search that 
exceeds the server size limit.  Has anyone been able to modify Turba to 
do this?  I tried

              }

but PHP complains that $driver->errno is an "undefined property".  I 
then tried

          return $this->getResults($fields, $res);

and now $driver->errno and $driver->errstr are blank.  I get the correct 
values in $this->errno and $this->errstr.  I tried issuing a 
raiseMessage unconditionally in search.php but this doesn't work since 
the displayed page is actually browse.php.
Any advice?
Thanks,
