Net::LDAP::Schema _must_or_may function

[Dave B. <da...@da...>]

Hello,

I have been having a little trouble with the 'must' and 'may' methods of
Net::LDAP::Schema.  Here is the error:

Can't use an undefined value as an ARRAY reference at
/usr/lib/perl5/site_perl/5.6.0/Net/LDAP/Schema.pm line 208.

It seems to happen when I call the method for an objectclass which has no
attributes of the desired type (MUST or MAY).  The error goes away when I
change line 208 from:

      @res{ @$res } = (); 	# Add in, getting uniqueness

to:

      @res{ @$res } = () if $res; 	# Add in, getting uniqueness

This way when I call $schema->may on an OC with no MAY attributes, for
example, the script does not crash.  I do not know if what I did is
correct, but it fixes the problem for me.
