Checking compile options
by Bryan Payne 05 Oct '10

05 Oct '10

I compiled two ldap servers quite some time ago and I can't remember what options I compiled in. I need to compile a new server and was wondering if there is a way to see what options I used previously?

What attributes to authenticate (or) How to block the ldap tree for anonymous users
by Holger Schier 05 Oct '10

05 Oct '10

Hey guys, I am working with the LSEE 11 and trying to run a LDAP server. From scratch on everything went fine. With the standard configuration I can login, but if I use the LDAP Browser and hit anonymous access, I can see my whole LDAP tree. User name, mailaddresses and so on. And I am not happy with it. So I tried to change the access control from access to * by * read to access to * by * auth or access to * by * search The user password is already in auth mode. But with every other configuration instead of read, I cannot login anymore. Insufficient access. After the first try with auth I read the log files and saw that there is a search operation. So i switched to search. Now the server denies some read operations. So, my questions are: Is it just normal that anyone can see the LDAP tree? Is there any other option to hide my tree? And what attributes have to be readable to login? Thanks a lot. Holger

How can I monitore a mirror mode?
by Tiago Cruz 05 Oct '10

05 Oct '10

Hello folks, I have 2 OpenLDAP 2.4.11 running as Mirror Mode very well. But I would like to make sure that everything was replicated how should be forever :) so I would like to write some script to monitor it. I've searched around web, but I only found some about LDAP 2.2 and 2.3 (syncrep). Can you give me some tip about how I can do this? Many thanks! -- -- Tiago Cruz

openldap vs. 389
by Matt Juszczak 05 Oct '10

05 Oct '10

Hi all, We are currently evaluating which directory server to use for our authentication implementation, pdns backend, and puppet backend. We have a proof of concept working with openldap but have recently begun looking into 389. For those who have worked with these two, which do you find to be better for your needs? Which has better replication options? What about community and active development? Any major features in one that isn't in the other that are important to you? Thanks, Matt

Fine Grained Permission System
by AdaXi 04 Oct '10

04 Oct '10

Hi everyone, I am kind of a newbie in OpenLDAP and LDAP in general, and I really need your help, I have been looking for a fine grained permission system to a project that I am in now, but could not find anything that satifies me. I have multiple applications that will authenticate using LDAP, but I also want to control user access in each application. I want to be able to allow specific acces to an element in one application. Examples : For database, I would like to assign read permissions to one or more database for one user. For a bulletin board, users can only post in some specifec boards. For a FTP server, users can only access specific directories. In first place is it realistic ? Do you know a way to do this only with LDAP ? (if yes, could you show me a manual or guide) Do you know some piece of software that could help me ? Thanks in advance, AdaXi

How to retrieve monitoring information
by Simon Gao 04 Oct '10

04 Oct '10

Hi, I am trying to retrieve information from monitoring database. However, the command like below does not return actual number for total connections. ldapsearch -x -D 'cn=admin,dc=xzy,dc=com' -W -b 'cn=Total,cn=Connections,cn=Monitor' Did I miss anything? or the command syntax is not right? Simon

Removing entries from cn=config
by Diego Lima 04 Oct '10

04 Oct '10

Hi all, I've been trying cn=config for some time now but I have a question: I can add/modify entries using ldapadd/ldapmodify, but so far I have not found a way to remove configurations without stopping slapd, going to slapd.d and manually removing the entry from there. What is the proper way to remove entries? If I try to remove the monitor database I get this error, for example: # ldapdelete -x -Dcn=admin,cn=config olcDatabase={2}monitor,cn=config -W Enter LDAP Password: ldap_delete: Server is unwilling to perform (53) I've tried to google it but had no success. Thank you! -- Diego Lima

Hi Cole, What does your /etc/nsswitch.conf look like? And your /etc/libnss-ldap.conf? 2010/9/27 Cole <colewashere(a)gmail.com>: > Sorry about the subject.

"Blank" node in multi-master OpenLDAP 2.4.21 setup (findbase failed)
by Mark Cairney 04 Oct '10

04 Oct '10

Hi, Apache Directory Studio appears to have FUBAR'ed one of the nodes in our multi-master OpenLDAP setup and I'd appreciate some help or pointers. Im running OpenLDAP 2.4.21 and BDB 4.8.26 with Kerberos 5 and GSSAPI SASL. On the "afflicted" node the DIT is empty other than the Root DSE and ldapsearch returns "32" no such object. The logs contain the following: ** ld 0x2aab4c4b7c70 Outstanding Requests: connection_get(44): got connid=1095 connection_read(44): checking for input on id=1095 * msgid 4, origid 4, status InProgress outstanding referrals 0, parent count 0 ldap_pvt_sasl_generic_install ld 0x2aab4c4b7c70 request count 1 (abandoned 0) ** ld 0x2aab4c4b7c70 Response Queue: ber_get_next Empty ld 0x2aab4c4b7c70 response count 0 ldap_chkResponseList ld 0x2aab4c4b7c70 msgid 4 all 0 ldap_chkResponseList returns ld 0x2aab4c4b7c70 NULL ldap_int_select ber_get_next: tag 0x30 len 292 contents: op tag 0x63, time 1286205781 ber_get_next conn=1095 op=3 do_search ber_scanf fmt ({miiiib) ber: >>> dnPrettyNormal: <dc=authorise,dc=ed,dc=ac,dc=uk> <<< dnPrettyNormal: <dc=authorise,dc=ed,dc=ac,dc=uk>, <dc=authorise,dc=ed,dc=ac,dc=uk> ber_scanf fmt (m) ber: ber_scanf fmt ({M}}) ber: => get_ctrls ber_scanf fmt ({m) ber: ber_scanf fmt (m) ber: => get_ctrls: oid="1.3.6.1.4.1.4203.1.9.1.1" (noncritical) ber_scanf fmt ({i) ber: ber_scanf fmt (m) ber: ber_scanf fmt (b) ber: ber_scanf fmt (}) ber: ber_scanf fmt ({m) ber: ber_scanf fmt (b) ber: => get_ctrls: oid="2.16.840.1.113730.3.4.2" (critical) <= get_ctrls: n=2 rc=0 err="" ==> limits_get: conn=1095 op=3 self="uid=replicator.authorise.is.ed.ac.uk,ou=people,ou=central,dc=authorise,dc=ed,dc=ac,dc=uk" this="dc=authorise,dc=ed,dc=ac,dc=uk" => bdb_search bdb_dn2entry("dc=authorise,dc=ed,dc=ac,dc=uk") bdb_dn2entry("cn=admins,ou=group,ou=central,dc=authorise,dc=ed,dc=ac,dc=uk") bdb_entry_get: rc=0 send_ldap_result: conn=1095 op=3 p=3 findbase failed! 32 send_ldap_result: conn=1095 op=3 p=3 send_ldap_response: msgid=4 tag=101 err=32 ber_flush2: 14 bytes to sd 44 connection_get(43): got connid=0 =>do_syncrepl rid=030 =>do_syncrep2 rid=030 ldap_result ld 0x2aab4c4b7c70 msgid 4 wait4msg ld 0x2aab4c4b7c70 msgid 4 (timeout 0 usec) wait4msg continue ld 0x2aab4c4b7c70 msgid 4 all 0 ** ld 0x2aab4c4b7c70 Connections: * host: alder.authorise.is.ed.ac.uk port: 636 (default) refcnt: 2 status: Connected last used: Mon Oct 4 16:23:01 2010 ** ld 0x2aab4c4b7c70 Outstanding Requests: * msgid 4, origid 4, status InProgress outstanding referrals 0, parent count 0 ld 0x2aab4c4b7c70 request count 1 (abandoned 0) ** ld 0x2aab4c4b7c70 Response Queue: Empty ld 0x2aab4c4b7c70 response count 0 ldap_chkResponseList ld 0x2aab4c4b7c70 msgid 4 all 0 ldap_chkResponseList returns ld 0x2aab4c4b7c70 NULL ldap_int_select read1msg: ld 0x2aab4c4b7c70 msgid 4 all 0 ber_get_next ber_get_next: tag 0x30 len 12 contents: read1msg: ld 0x2aab4c4b7c70 msgid 4 message type search-result ber_scanf fmt ({eAA) ber: read1msg: ld 0x2aab4c4b7c70 0 new referrals read1msg: mark request completed, ld 0x2aab4c4b7c70 msgid 4 request done: ld 0x2aab4c4b7c70 msgid 4 res_errno: 32, res_error: <>, res_matched: <> ldap_free_request (origid 4, msgid 4) ldap_parse_result ber_scanf fmt ({iAA) ber: ber_scanf fmt (}) ber: ldap_err2string do_syncrep2: rid=030 LDAP_RES_SEARCH_RESULT (32) No such object ldap_err2string ldap_err2string do_syncrep2: rid=030 (32) No such object ldap_err2string ldap_msgfree connection_get(43): got connid=0 ldap_free_connection 1 1 ldap_send_unbind ber_flush2: 7 bytes to sd 43 connection_get(44): got connid=1095 connection_read(44): checking for input on id=1095 ber_get_next TLS trace: SSL3 alert write:warning:close notify ldap_free_connection: actually freed ber_get_next: tag 0x30 len 5 contents: op tag 0x42, time 1286205781 ber_get_next do_syncrepl: rid=030 rc -2 retrying TLS trace: SSL3 alert read:warning:close notify ber_get_next on fd 44 failed errno=0 (Success) conn=1095 op=4 do_unbind connection_close: conn=1095 sd=44 TLS trace: SSL3 alert write:warning:close notify So far to fix it I've tried running slapd with the "-c rid=" option, deleting the contents of /var/openldap-data, running db_verify and db_recover (with and without the -c flag) and doing a slapadd from one of the other working nodes but nothing has worked. Interestingly the file sizes in /var/openldap-data/authorise look OK but the LDAP tree appears to have vanished without a trace. Any ideas?
