I think this is the intended behaviour. The code always fetches a single
value for the named attribute. This means it always gets the first
attribute's value. It does not try to fetch all values of the named
attribute.
Currently you could use a PostSearchHook to do something like this:
my @ldap_groups = $p->get_attr('OSC-Group-Identifier-LDAP');
Since @ldap_groups is an array, you will get all values of
OSC-Group-Identifier-LDAP, not just the first one.
Then you can try each LDAP memberOf attribute value with
OSC-Group-Identifer-LDAP attribute values to see if there's a match:
my $memberof = $entry->get_value('memberOf', asref => 1);
foreach my $group (@$memberof) {
return 1 if (map {lc $group eq lc $_} @ldap_groups);
}
return 0;
Also, we discussed here about adding support for RADIUS attributes that
can be present multiple times. This would mean that e.g., if there are 4
Framed-IP-Address attributes, you could have something like this (flat
file format):
mikem User-Password=fred, %{RequestOr:Framed-IP-Address}=1.2.3.4
This would pass if any of the 4 Framed-IP-Address attributes is 1.2.3.4.
Any comments about how useful you or the others would see this is
appreciated.
