start_tls generating 0x01 LDAP_OPERATIONS_ERROR

[Drew R. <dr...@ph...>]

I have a working script with changes users passwords in an OpenLDAP
2.0.18 database.  Using version 0.25 of perl-ldap.

However, I get an Operations error when I try to start_tls.  Here's the
snippet of code:

   my $ldap = Net::LDAP->new( 'ldap.phg.mc.vanderbilt.edu', version=>3,
				 debug=>12 ) or error_msg($@);
   my $mesg = $ldap->start_tls(  verify=>'optional',
				  cafile=>"$cafile" );
   error_msg( $mesg->code . "/" . $mesg->error );
   $mesg = $ldap->bind( "uid=$username,ou=people,$DN",
				 password=>$cur_pass) or error_msg($@);

The $ldap->start_tls is what generates the error.

I captured the output of the attempt, but don't know what it means.

   root@mays ( ~ )$ cat /tmp/ldappw_tls 
   Net::LDAP=HASH(0x333a4c) sending:

   0002    1:   INTEGER = 1

   001F     : }

   000C    0:     STRING = ''
   000E     :   }
   000E     : }

What's going on?
