Ticket 48681 - Use of uninitialized value in string ne at /usr/bin/logconv.pl line 2565, <$LOGFH> line 4
    
    Bug description:  The original fix for 48681 added a regression in regards to perl
                      warning everytime you ran the script.  That was due to a new hash
                      for sasl binds that was not initialized.
    
    Fix Description:  Check is the saslbind hash "exists" before checking its value.
