Virtual list view problem
by Venish Khant 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

Certificate authentication and back-ldap proxy
by Ubay Dorta Guerra 27 Dec '10

27 Dec '10

Hi, We have some problems with certificate authentication when the master server is behind a back-ldap proxy. We have openldap 2.4.21 on Suse Linux Enterprise Server 10 SP3 and these are the details of our scenario: The master server: server1.example.com has the following slapd.conf file: access to dn.base="" by * read access to dn.base="cn=Subschema" by * read access to attrs=userPassword,userPKCS12 by self write by dn.exact="CN=admin_w_cert,O=Internet Widgits Pty Ltd,ST=Some-State,C=AU" read by * auth access to attrs=shadowLastChange by self write by * read access to * by * read # # Security SSL # TLSCipherSuite HIGH:MEDIUM:+SSLv3 TLSCertificateFile /etc/ssl/certs/server1.example.com.pem TLSCertificateKeyFile /etc/ssl/private/server1.example.com.key TLSCACertificatePath /etc/ssl/cacerts/ TLSVerifyClient demand # #Log level # loglevel 256 # Require authentication require authc ####################################################################### # HDB database definitions ####################################################################### database hdb suffix "dc=example,dc=com" checkpoint 1024 5 cachesize 10000 rootdn "cn=Manager,dc=example,dc=com" rootpw secret # Indices to maintain index objectClass eq # Overlay ppolicy overlay ppolicy ---------------------- Authentication is required, and we give access to the user passwords for the dn of a certificate. When we search for passwords using the certificate we get the following: root# ldapsearch -LLL -b 'uid=user_w_pass,ou=people,dc=example,dc=com' -H ldaps://server1.example.com userPassword SASL/EXTERNAL authentication started SASL username: CN=admin_w_cert,O=Internet Widgits Pty Ltd,ST=Some-State,C=AU SASL SSF: 0 dn: uid=user_w_pass,ou=people,dc=example,dc=com userPassword:: e2NyeXB0fTcyMXpQbU4waWdKaU0= ----------------------- The root user (ldap client) has a ~/.ldaprc file with: TLS_CACERTDIR /etc/ssl/cacerts/ TLS_CERT /etc/ssl/certs/admin_w_cert.pem TLS_KEY /etc/ssl/private/admin_w_cert.key TLS_REQCERT demand SASL_MECH EXTERNAL In /var/log/messages we get: ldap-master[22358]: conn=1000 fd=11 ACCEPT from IP=server1.example.com:40899 (IP=server1.example.com:636) ldap-master[22358]: conn=1000 fd=11 TLS established tls_ssf=256 ssf=256 ldap-master[22358]: conn=1000 op=0 BIND dn="" method=163 ldap-master[22358]: conn=1000 op=0 BIND authcid="cn=admin_w_cert,o=internet widgits pty ltd,st=some-state,c=au" authzid="cn=admin_w_cert,o=internet widgits pty ltd,st=some-state,c=au" ldap-master[22358]: conn=1000 op=0 BIND dn="cn=admin_w_cert,o=internet widgits pty ltd,st=some-state,c=au" mech=EXTERNAL sasl_ssf=0 ssf=256 ldap-master[22358]: conn=1000 op=0 RESULT tag=97 err=0 text= ldap-master[22358]: conn=1000 op=1 SRCH base="uid=user_w_pass,ou=people,dc=example,dc=com" scope=2 deref=0 filter="(objectClass=*)" ldap-master[22358]: conn=1000 op=1 SRCH attr=userPassword ldap-master[22358]: conn=1000 op=1 SEARCH RESULT tag=101 err=0 nentries=1 text= ldap-master[22358]: conn=1000 op=2 UNBIND ldap-master[22358]: conn=1000 fd=11 closed This is the correct behavior for us. The problem appears when we introduce a back-ldap proxy between the client and the master.

Multi master replication

Hi All, I have configured two servers with multi master replication. Below is my configuration for synrepl on both servers. Server One ------------ serverID 001 overlay syncprov syncprov-checkpoint 100 10 syncrepl rid=000 provider=ldap://192.168.10.100 type=refreshAndPersist retry="5 5 300 +" searchbase="dc=example,dc=com" attrs="*,+" bindmethod=simple binddn="cn=syncuser,dc=example,dc=com" credentials=password mirrormode TRUE Server Two -------------- serverID 002 overlay syncprov syncprov-checkpoint 100 10 syncrepl rid=000 provider=ldap://192.168.10.25 type=refreshAndPersist retry="5 5 300 +" searchbase="dc=example,dc=com" attrs="*,+" bindmethod=simple binddn="cn=syncuser,dc=example,dc=com" credentials=password mirrormode TRUE Today one of user said that he was not able to login. So i checked in the servers in one server i was able to login but on another server i was not able to login with the same password. I have checked the contextCSN on both server they are equal. In the log it is showing this syncrepl_entry: rid=000 entry unchanged, ignored (uid=user,ou=People,dc=example,dc=com) Apr 28 12:14:17 mails slapd[16595]: syncrepl_entry: rid=000 uid=user,ou=People,dc=example,dc=com Apr 28 12:14:17 mails slapd[16595]: syncrepl_entry: rid=000 be_add uid=user,ou=People,dc=example,dc=com (68) Apr 28 12:14:17 mails slapd[16595]: dn_callback : entries have identical CSN uid=user,ou=People,dc=example,dc=com 20100422132507.789242Z#000000#002#000000 Can anyone help me why above message is showing in the log files and why the user is not able to login.

smbk5pwd: ldappassword hangs
by Frank Van Damme 18 Jun '10

18 Jun '10

Hi list, I installed and configured the smbk5pwd overlay as described on http://student.physik.uni-mainz.de/~reiffert/smbk5pwd.html#smbk5pwd. This succeeded, the module is loaded etc. But an unwelcome side effect is that password changes don't function anymore. With the overlay/module disabled, there is no problem; if I enable it, the "ldappasswd" command hangs. I marked where I hit Ctrl-C on the hanging ldappasswd command. This is the slapd log... daemon: activity on 1 descriptor daemon: activity on: slap_listener_activate(7): daemon: epoll: listen=7 busy >>> slap_listener(ldap://127.0.0.1/) daemon: epoll: listen=8

Bidirectional sync using openldap and active directory
by Benjamin MONTHOUEL 07 Jun '10

07 Jun '10

Hi, I'd like to know which method is recommended by openldap.org to perform a bidirectional sync with Microsoft Active Directory. This method has to notice that users changed their password by themselves. Kerberos token ??? Thanks for any information. -- Benjamin MONTHOUËL Systems Administrator Assistant NETASQ France - We Secure IT Villeneuve d'Ascq

replication issue
by Lennart Job 01 Jun '10

01 Jun '10

Hi there, I've got some problems with ldap replication. Ever since I've updated the master from Debian Etch to Lenny changes are no longer synced. I've got v2.4.11 running on both servers. The slave is still running Etch. SSL is active, so maybe there's a problem with the certificates... However, if I restart the slave slapd he does replicate properly. Do you know any reasons for this behavior? In addition, synchronization with samba on the master doesn't work properly anymore. I can create accounts but password changes don't take effect. So everybody has to use his first ever password to connect to samba... Thanks for your help! Kind regards, Lennart -- Lennart Job Ressort IT / Wissensmanagement fuks e.V.

Server certificate
by Daniel Gomes 01 Jun '10

01 Jun '10

Hey there, I've got a simple enough question: is it possible to use a certificate for TLS (through the TLSCertificateFile directive) on which the FQDN of the LDAP server is not on the CN but instead on the alternative name? I tried this, but I'm getting a "TLS init def ctx failed: -64" and I thought it might be because of this issue. I also couldn't find a list of the error numbers and their descriptions, making it harder for me to understand what's wrong...

Re: Q: status of component matching?
by Lehnert, Hartmut 31 May '10

31 May '10

Hi all! To avoid the slapd's core dump when using component match filters (see ITS # 6556) I removed line 556 of file "servers/slapd/filter.c": case LDAP_FILTER_EXT: //mra_free( op, f->f_mra, 1 ); break; Now component match filter search requests are answered by slapd but don't work correctly. In fact nothing is found! For example the request /home/openldap/openldap-2.4.21-install/bin/ldapsearch -h localhost -p 9389 -D cn=openldapadmin -w welcome -b o=CustomerCA,c=de -s sub "(userCertificate:componentFilterMatch:=item:{ component \"toBeSigned.serialNumber\", rule allComponentsMatch, value 449 })" sncertnr Is answered with # extended LDIF # # LDAPv3 # base <o=CustomerCA,c=de> with scope subtree # filter: (userCertificate:componentFilterMatch:=item:{ component "toBeSigned.serialNumber", rule allComponentsMatch, value 449 }) # requesting: sncertnr # # search result search: 2 result: 0 Success # numResponses: 1 But in the database of slapd there are several certificates with serialNumber 449: lehnert.hartmut@sn-ocspr4:/opt/lehnert/Openldap-Support$ ./dumpasn1 449.cer 0 30 702: SEQUENCE { 4 30 551: SEQUENCE { 8 A0 3: [0] { 10 02 1: INTEGER 2 : } 13 02 2: INTEGER 449 17 30 13: SEQUENCE { 19 06 9: OBJECT IDENTIFIER : sha256WithRSAEncryption (1 2 840 113549 1 1 11) 30 05 0: NULL : } 32 30 111: SEQUENCE { 34 31 11: SET { 36 30 9: SEQUENCE { 38 06 3: OBJECT IDENTIFIER countryName (2 5 4 6) 43 13 2: PrintableString 'DE' : } : } 47 31 12: SET { On slapd's side the debug message bdb_search: <integer> does not match filter is written out for every record. What's going wrong here? Regards, Hartmut

Hello, I installed a server (RHEL5 x86_64) with three instances of OpenLDAP 2.3.43. ldap 6572 1 0 May24 ? 00:49:12 /usr/sbin/slapd -u ldap -g ldap -h ldap://X.Y.Z.104:389 -f /etc/openldap/slapd.conf -l LOCAL4ldap 6612 1 0 May24 ? 00:49:09 /usr/sbin/slapd -u ldap -g ldap -h ldap://X.Y.Z.105:389 -f /etc/openldap/slapd_i3.conf -l LOCAL6ldap 8031 1 0 01:01 ? 00:01:26 /usr/sbin/slapd -u ldap -g ldap -h ldap://X.Y.Z.104:389 -f /etc/openldap/slapd_i2.conf -l LOCAL5 At first everything worked perfect but after several days working properly one instance stopped.I started the instance again but after several days one instance stopped (not the same).I don't understand what happens. Any help is very useful to me.
