Virtual list view problem
by Venish Khant 31 May '16

31 May '16

Hi all I am using cpan Net::LDAP module to access LDAP entries. I want to search LDAP entries using Net::LDAP search method. When I do search, I want some limited number of entries from search result, for this(searching) process I am using Net::LDAP::Control::VLV module. But I get error on VLV response control. Please, any one have idea about this error. * Error:* Died at vlv.pl line 50, This is my example. I changed the font style of line 50 #!/usr/bin/perl -w use Net::LDAP; use Net::LDAP::Control::VLV; use Net::LDAP::Constant qw( LDAP_CONTROL_VLVRESPONSE ); use Net::LDAP::Control::Sort; sub procentry { my ( $mesg, $entry) = @_; # Return if there is no entry to process if ( !defined($entry) ) { return; } print "dn: " . $entry->dn() . "\n"; @attrs = $entry->attributes(); foreach $attr (@attrs) { #printf("\t%s: %s\n", $attr, $entry->get_value($attr)); $attrvalue = $entry->get_value($attr,asref=>1); #print $attr.":". $entry->get_value($attr)."\n"; foreach $value(@$attrvalue) { print "$attr: $value\n"; } } $mesg->pop_entry; print "\n"; } $ldap = Net::LDAP->new( "localhost" ); # Get the first 20 entries $vlv = Net::LDAP::Control::VLV->new( before => 0, # No entries from before target entry after => 19, # 19 entries after target entry content => 0, # List size unknown offset => 1, # Target entry is the first ); my $sort = Net::LDAP::Control::Sort->new( order => 'cn' ); @args = ( base => "dc=example,dc=co,dc=in", scope => "subtree", filter => "(objectClass=inetOrgPerson)", callback => \&procentry, # Call this sub for each entry control => [ $sort, $vlv ], ); $mesg = $ldap->search( @args ); # Get VLV response control *($resp) = $mesg->control( LDAP_CONTROL_VLVRESPONSE ) or die;* $vlv->response( $resp ); # Set the control to get the last 20 entries $vlv->end; $mesg = $ldap->search( @args ); # Get VLV response control ($resp) = $mesg->control( LDAP_CONTROL_VLVRESPONSE ) or die; $vlv->response( $resp ); # Now get the previous page $vlv->scroll_page( -1 ); $mesg = $ldap->search( @args ); # Get VLV response control ($resp) = $mes # Now page with first entry starting with "B" in the middle $vlv->before(9); # Change page to show 9 before $vlv->after(10); # Change page to show 10 after $vlv->assert("B"); # assert "B" $mesg = $ldap->search( @args );g->control( LDAP_CONTROL_VLVRESPONSE ) or die; $vlv->response( $resp ); -- Venish Khant www.deeproot.co.in

dynlist overlay feature request
by Alexander 'Leo' Bergolth 02 Dec '09

02 Dec '09

Are there any plans to extend the dynlist overlays dynamic group feature to return not the DNs of the matched entries but an attribute of the entries? This would be useful for defining dynamic groups based on posixGroup (which need only the username, not the full DN) and populating them with entries from posixAccounts. If the dynlist-attrset could be extended by one parameter like: dynlist-attrset <group-oc> <URL-ad> [<member-ad>] [<result-ad>] ... where the additional parameter specifies the attribute that should be returned from the search results, a dynamic posixGroup could be configured like that: dynlist-attrset myposixGroup memberURL memberUid uid with a search filter like that: ldap:///ou=users,dc=local,dc=site??sub?(&(objectClass=posixAccount)(<searchfilter>)) I.e. "take the uid attribute of the matched entries and add them as memberUid." Could this extension be easily implemented? Is there currently any workaround? E.g. a way to dynamically add a memberUid to each posixAccount that contains the same data as the uid attribute? If that works, a filter like ldap:///ou=users,dc=local,dc=site?memberUid?sub?(&(objectClass=posixAccount)(<searchfilter>)) ... could work.

defining own attributes/class
by Zdenek Styblik 27 Oct '09

27 Oct '09

Hello, I would like to ask, if somebody knows a really good how-to about $subj. I've read couple books, let's say I'm able to define my own attribute, even extend some existing object - I think these are no problem, as they are based on trying right-wrong. My biggest concern is about numbering [OID/PEN ?]. I've requested PEN from IANA, no problem here. But how should I divide numbers to attributes? Does it matter? Can I run out of space? Do something [utterly] wrong? I just haven't seen this [numbering] explained to the last bit anywhere. Or may be, I've just read wrong. I mean, should it be like tree structure and eg. class1 = prefix.PEN.1.X; class2 = prefix.PEN.2.X; ...; classN = prefix.PEN.N.X; ? But may be there is no "bigger" sense I'm looking for and incremental numbering (+1 per attribute) is just enough. PS: for example, I would like to add JID [jabber ID]/IM [which would hold whatever Instant Messaging string] attribute and extend InetOrgPerson with this attribute. Thanks in advance for explanation/pointing me to the right direction.

Making copies of attribute values
by Ravi Verma 27 Oct '09

27 Oct '09

Dear Friends, I have a need to extend an LDAP schema by adding an attribute and copy the value from an existing attribute to it. We need to keep the two copies of the attribute values in synch. It is a kind of replication where it is replicating one attribute into another in the same record. I appreciate your help. -- Kind regards.
