how to tell client to use ssf=256 instead of ssf=128
by Tobias Hachmer 08 Oct '12

08 Oct '12

Hello, I'm using openldap 2.4.28 on ubuntu server and configured TLS. I want to allow write operations only when ssf=256 is used. (security update_ssf=256) Certificates were set up with openssl CA.pl. When I connect via # ldapadd -Y EXTERNAL -ZZ -f /src/test.ldif I get this: SASL/EXTERNAL authentication started SASL username: cn=ldapadmin,............. SASL SSF: 0 adding new entry "dc=example,dc=com" ldap_add: Confidentiality required (13) additional info: stronger confidentiality required for update the log says: Oct 8 19:38:14 ldap slapd[2205]: conn=1003 fd=13 ACCEPT from IP=127.0.0.1:56698 (IP=0.0.0.0:389) Oct 8 19:38:14 ldap slapd[2205]: conn=1003 op=0 EXT oid=1.3.6.1.4.1.1466.20037 Oct 8 19:38:14 ldap slapd[2205]: conn=1003 op=0 STARTTLS Oct 8 19:38:14 ldap slapd[2205]: conn=1003 op=0 RESULT oid= err=0 text= Oct 8 19:38:14 ldap slapd[2205]: conn=1003 fd=13 TLS established tls_ssf=128 ssf=128 Oct 8 19:38:14 ldap slapd[2205]: conn=1003 op=1 BIND dn="" method=163 Oct 8 19:38:14 ldap slapd[2205]: conn=1003 op=1 BIND authcid="cn=ldapadmin,........." authzid="cn=ldapadmin,........"

Why is the client connecting with ssf=128? 2. Can I influence the ssf used by client, if yes, how? 3. Maybe a certificate issue? Thanks in advance, Tobias Hachmer

Complete re-sync in MirrorMode
by Santosh Kumar Gupta 07 Oct '12

07 Oct '12

Dear List, I set up two openldap servers in MirrorMode replication. I addeed a user in Master2 and it synced in Master1 but without userPassword. Digging into the problem I found a typo error in olcAccess for replicator user. I fixed the error and any new updates in Master2 get updated in Master1 including userPassword, but not syncing the previously replicated users. I tried running slapd with parameter -c "rid=000" but without success. Please help me to full sync Master1 without recreating db. TIA Santosh

Openldap Synchronization Issue
by Victor Silva 06 Oct '12

06 Oct '12

Hello folks, I have an ldap base running in 2 machines in a master/slave design. I've tried to do a db2ldiff but as I'm using virtual machines it took a very long time and I aborted the process with crtl C. Since them my bases no longer sync. I have the following erros logs: *[05/Oct/2012:17:44:22 -0300] - 389-Directory/1.2.9.9 B2011.244.2040 starting up [05/Oct/2012:17:44:22 -0300] - from ldbm instance init: line 0: unknown or invalid matching rule "integerOrderingMatch" in index configuration (ignored) [05/Oct/2012:17:44:22 -0300] - from DSE add: line 0: unknown or invalid matching rule "integerOrderingMatch" in index configuration (ignored) [05/Oct/2012:17:44:22 -0300] - from ldbm instance init: line 0: unknown or invalid matching rule "integerOrderingMatch" in index configuration (ignored) [05/Oct/2012:17:44:22 -0300] - from DSE add: line 0: unknown or invalid matching rule "integerOrderingMatch" in index configuration (ignored) *I've read in some other mailing lists many people had this problem but I could not pint point an appropriate solution. I don't know which other logs I can post in order to help you but I will be happy to provide them if you require more info. Regards, vfbsilva

pwdReset: TRUE not working
by Jason Cwik 05 Oct '12

05 Oct '12

Hi, I've recently configured a new openldap 2.4.32 server with the ppolicy overlay. Most of the features like lockout and minLength work fine, but I can't seem to force the user's password to expire. I've even set pwdReset: TRUE on the user's record to try and force them to reset the password, but it doesn't seem to do anything. Here's my overlay config: MBP2:~ me$ ldapsearch -h 10.242.25.158 -D "cn=root,cn=config" -x -W -b "cn=config" -s sub "olcOverlay=ppolicy" Enter LDAP Password: # extended LDIF # # LDAPv3 # base <cn=config> with scope subtree # filter: olcOverlay=ppolicy # requesting: ALL # # {1}ppolicy, {1}bdb, config dn: olcOverlay={1}ppolicy,olcDatabase={1}bdb,cn=config objectClass: olcOverlayConfig objectClass: olcPPolicyConfig olcOverlay: {1}ppolicy olcPPolicyDefault: cn=default,ou=policies,dc=my,dc=domain,dc=com # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 And the default pwdPolicy object: MBP2:~ me$ ldapsearch -h 10.242.25.158 -D "cn=ldapadmin,dc=my,dc=domain,dc=com" -x -W -b "ou=policies,dc=my,dc=domain,dc=com" -s sub "cn=default" Enter LDAP Password: # extended LDIF # # LDAPv3 # base <ou=policies,dc=my,dc=domain,dc=com> with scope subtree # filter: cn=default # requesting: ALL # # default, policies, my.domain.com dn: cn=default,ou=policies,dc=my,dc=domain,dc=com objectClass: person objectClass: top objectClass: pwdPolicy cn: default pwdAllowUserChange: TRUE pwdAttribute: 2.5.4.35 pwdCheckQuality: 2 pwdExpireWarning: 0 pwdFailureCountInterval: 30 pwdInHistory: 5 pwdLockout: TRUE pwdLockoutDuration: 300 pwdMaxAge: 11555200 pwdMaxFailure: 5 pwdMinAge: 0 pwdMinLength: 5 pwdMustChange: TRUE pwdSafeModify: TRUE sn: dummy value I turned on trace debugging and I do see it successfully loading cn=default,ou=policies,dc=my,dc=domain,dc=com during the bind operation, so it appears that ppolicy is running fine and loading the policy object. Any ideas?

Can not build OpenLDAP with OpenSSL in custom location
by jckidder＠aep.com 05 Oct '12

05 Oct '12

Ok, this is driving me nuts!!!! I can't build OpenLDAP with TLS support. configure fails with a TLS/SSL error. If I disable TLS everything works just fine. Everthing I can find on the net is telling me I'm doing this right but it's not working. I have OpenSSL 0.9.8x built and installed to a custom directory: /appl/openssl I have the following environment variables set: LD_LIBRARY_PATH=/appl/BerkeleyDB/lib:/appl/openssl/lib:/appl/cyrus_sasl/lib:/appl/unixODBC/lib:/appl/openldap/lib:$LD_LIBRARY_PATH CPPFLAGS="-I/appl/BerkeleyDB/include -I/appl/openssl/include/openssl -I/appl/cyrus_sasl/include -I/appl/unixODBC/include -I/appl/openldap/include -I/usr/include -DF00=42" LDFLAGS="-L/appl/BerkeleyDB/lib -L/appl/openssl/lib -L/appl/cyrus_sasl/lib -L/appl/unixODBC/lib -L/appl/openldap/lib -L/usr/lib " I run the following configure command: ./configure --prefix=/appl/openldap --enable-bdb --enable-ldap --enable-sql --enable-overlays --enable-spasswd --with-tls=openssl And I get the following output: checking openssl/ssl.h usability... yes checking openssl/ssl.h presence... yes checking for openssl/ssl.h... yes checking for SSL_library_init in -lssl... no checking for ssl3_accept in -lssl... no configure: error: Could not locate TLS/SSL package What am I missing?? -Jon C.

What does acl-bind exactly
by General Stone 05 Oct '12

05 Oct '12

Hello, what does acl-bind exactly in ldap backend (slapd-ldap)? I don't understand the explenataion in available documentations. The manpage says "... that is internally used by the proxy to collect info related to access control ...", but which informations are needed from the remote server? Further the manpage says "The identity (...) is supposed to have read access on the target server to attributes used on the proxy for ACL checking ...", but which attributes are mean? Kind regards, Markus Martinet -- Key fingerprint = A0D9 F306 0FC0 30E7 62DB E785 A192 2A30 5CF1 224D ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Die Theorie ist immer nur so gut wie ihre Praxis. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Filter a ldap connection for a user comming from an IP source
by Mik J 05 Oct '12

05 Oct '12

Hello, I have this ACL that allows the users myadmin to list encrypted passwords access to attrs=userpassword,shadowMax,shadowExpire,sambaLMPassword,sambaNTPassword,sambaPwdLastSet by dn="uid=myadmin,ou=people,dc=mydomain,dc=org" read However this user my admin is supposed to come from one IP 1.1.1.1 only. I think that the peername directive might help to achive this task but I don't know how to associate it with the user myadmin. In conclusion I would like that the user myadmin coming from IP 1.1.1.1 be able to see the encrypted passwords. If the user myadmin comes from another IP like 2.2.2.2 he would not match the ACL and therefore not be able to see encrypted passwords. Does anyone know what is the syntax ?

LDAP Stopped Authenticating Samba Shares
by Steve Olszewski 04 Oct '12

04 Oct '12

Hi All-- I'm a fairly new Systems Administrator at my company, and have inherited a mostly undocumented infrastructure, including LDAP and Samba. We had been using LDAP for authentication, allowing access to the Samba shares based on group membership. Recently, users were unable to mount shares, as authentication had broken somehow. A couple of things stand out: 1) Using phpldapadmin, if I compare the sambalmpasswd or the sambantpasswd on any account to the password that *should* be in place, I get a "passwords do not match" error. The standard user password checks out OK, however. I'm not sure why this is happening. 2) Samba will not start. It dies with a "smbd[2902]: ERROR: failed to setup guest info." error. As far as I can tell, this happens when Samba starts and tries to find the "nobody" user, both locally and on the remote LDAP server. The nobody user exists in both places, and I can run 'getent passwd' and 'getent group' and see both local and LDAP users/groups. I am having a terrible time troubleshooting this, and wonder if someone might have an idea about what's going on, or point me in the right direction. Best, Steve Olszewski

Re: Access denied consumer replication (OpenLDAP+Kerberos)
by Daniel Lopes de Carvalho 04 Oct '12

04 Oct '12

Hi Quanah. Thanks for your reply! I was following this link to configure the provider/consumer: http://www.rjsystems.nl/en/2100-d6-kerberos-openldap-consumer.php. Under item "2. Kerberos client install", at the end, I was guided to create a principal starting with ldap/dns02... But... I created 3 principals: host/dns02... ldap/dns02.. and ldaps/dns02... And under item "8. Provider modifications" I was instruted to map uid=ldap/... to ou=consumers # 1.2.1. add: olcAuthzRegexp olcAuthzRegexp: uid=ldap/([^/\.]+).example.com,cn=example.com,cn=gssapi,cn=auth cn=$1,ou=consumers,dc=example,dc=com I deleted the principals host/dns02... and ldaps/dns02... and the replication started to work. Thanks very mch!

Problem converting slapd.conf to cn=config format
by Patrick Lists 04 Oct '12

Hi all, New to the list and (Open)LDAP so apologies if I'm missing the obvious. I've gone through the Admin Guide and some other docs I found online but I still have problems converting a slapd.conf to the cn=config format on a CentOS 6.3 x86_64 box with openldap-2.4.23-26.el6_3.2 $ cat ~/slapd.conf.new # general parameters include /etc/openldap/schema/corba.schema include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/duaconf.schema include /etc/openldap/schema/dyngroup.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/java.schema include /etc/openldap/schema/misc.schema include /etc/openldap/schema/nis.schema include /etc/openldap/schema/openldap.schema include /etc/openldap/schema/ppolicy.schema include /etc/openldap/schema/collective.schema allow bind_v2 loglevel 296 pidfile /var/run/openldap/slapd.pid argsfile /var/run/openldap/slapd.args password-hash {SSHA} modulepath /usr/lib64/openldap TLSCipherSuite HIGH TLSCACertificatePath /etc/openldap/certs TLSCertificateFile "\"OpenLDAP Server\"" TLSCertificateKeyFile /etc/openldap/certs/password lastmod on # databases database config rootdn "cn=admin,cn=config" rootpw {SSHA}LDeTJEEBhqypKL2FpQuFc2j4Na1TLTRW access to * by dn.exact="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" manage by * none # enable server status monitoring (cn=monitor) database monitor access to * by dn.exact="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" read by dn.exact="cn=admin,dc=example,dc=com" read by * none database hdb suffix "dc=example,dc=com" rootdn "cn=admin,dc=example,dc=com" rootpw {SSHA}LDeTJEEBhqypKL2FpQuFc2j4Na1TLTRW mode 600 checkpoint 512 30 cachesize 2097152 index uid pres,eq index cn,sn,mail pres,eq,approx,sub index objectClass eq directory /var/lib/ldap Steps I did: # service slapd stop # rm -rf /var/lib/ldap/* # rm -rf /etc/openldap/slapd.d/* # cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG # echo "" | slapadd -v -d 448 -f ./slapd.conf.new # slaptest -v -d 448 -f ./slapd.conf.new -F /etc/openldap/slapd.d The last step just hangs and does not do anything even after waiting 45 minutes.
