Creating samba3 users with phpldapadmin
by Juan Diego Calle 10 Oct '11

10 Oct '11

Hi I have a problem with samba3 users created over phpldapadmin, the users created over phpldapadmin can log in from their windows machines. I if try to use smbclient to log I receive this NT_STATUS_PASSWORD_MUST_CHANGE if I try to change the password with smbldap-passwd I receive this Failed to modify shadowLastChange: attribute 'shadowLastChange' not allowed at /usr/sbin/smbldap-passwd line 292, <STDIN> line 2. Failed to modify shadowMax: attribute 'shadowMax' not allowed at /usr/sbin/smbldap-passwd line 299, <STDIN> line 2. So looking around it seems like the problem is that users dont have the objectClass shadowAccount. It seems that phpldapadmin doesnt use. When I add the objectClass shadow account, from windows, I manage to log on to windows the first time then It asks me to change the password, then I can log in anymore. For some reason all the users created from phpldapadmin have the uid 1000, i changed one from my test users to 6000 but i have the same results: windows users: The User name or password is incorrect. When use smbclient i have no problems listing the file. I can find any error on samba or ldap. This is the log when I try to log with the user "testuser2" 6927679-Oct 10 17:06:27 prosrvuiosmb151 slapd[13037]: <= bdb_equality_candidates: (sambaSID) not indexed 6927680-Oct 10 17:06:27 prosrvuiosmb151 slapd[13037]: conn=52 op=38 SEARCH RESULT tag=101 err=0 nentries=0 text= 6927681-Oct 10 17:06:27 prosrvuiosmb151 slapd[13037]: conn=52 op=39 SRCH base="dc=mydomain,dc=com,dc=ec" scope=2 deref=0 filter="(&(objectClass=sambaGroupMapping)(sambaSID=s-1-5-2))" 6927682-Oct 10 17:06:27 prosrvuiosmb151 slapd[13037]: conn=52 op=39 SRCH attr=gidNumber sambaSID sambaGroupType sambaSIDList description displayName cn objectClass 6927683-Oct 10 17:06:27 prosrvuiosmb151 slapd[13037]: <= bdb_equality_candidates: (sambaSID) not indexed 6927684-Oct 10 17:06:27 prosrvuiosmb151 slapd[13037]: conn=52 op=39 SEARCH RESULT tag=101 err=0 nentries=0 text= 6927685-Oct 10 17:06:27 prosrvuiosmb151 slapd[13037]: conn=52 op=40 SRCH base="dc=mydomain,dc=com,dc=ec" scope=2 deref=0 filter="(&(objectClass=sambaGroupMapping)(sambaSID=s-1-5-11))" 6927686-Oct 10 17:06:27 prosrvuiosmb151 slapd[13037]: conn=52 op=40 SRCH attr=gidNumber sambaSID sambaGroupType sambaSIDList description displayName cn objectClass 6927687-Oct 10 17:06:27 prosrvuiosmb151 slapd[13037]: <= bdb_equality_candidates: (sambaSID) not indexed 6927688-Oct 10 17:06:27 prosrvuiosmb151 slapd[13037]: conn=52 op=40 SEARCH RESULT tag=101 err=0 nentries=0 text= 6927689:Oct 10 17:06:34 prosrvuiosmb151 slapd[13037]: conn=5 op=697 SRCH base="dc=mydomain,dc=com,dc=ec" scope=2 deref=0 filter="(&(objectClass=posixAccount)(uid=testuser2))" 6927690-Oct 10 17:06:34 prosrvuiosmb151 slapd[13037]: conn=5 op=697 SRCH attr=uid userPassword uidNumber gidNumber cn homeDirectory loginShell gecos description objectClass 6927691-Oct 10 17:06:34 prosrvuiosmb151 slapd[13037]: conn=5 op=697 SEARCH RESULT tag=101 err=0 nentries=1 text= 6927692-Oct 10 17:06:37 prosrvuiosmb151 slapd[13037]: conn=52 op=41 SRCH base="dc=mydomain,dc=com,dc=ec" scope=2 deref=0 filter="(&(uid=administrator)(objectClass=sambaSamAccount))" 6927693-Oct 10 17:06:37 prosrvuiosmb151 slapd[13037]: conn=52 op=41 SRCH attr=uid uidNumber gidNumber homeDirectory sambaPwdLastSet sambaPwdCanChange sambaPwdMustChange sambaLogonTime sambaLogoffTime sambaKickoffTime cn sn displayName sambaHomeDrive sambaHomePath sambaLogonScript sambaProfilePath description sambaUserWorkstations sambaSID sambaPrimaryGroupSID sambaLMPassword sambaNTPassword sambaDomainName objectClass sambaAcctFlags sambaMungedDial sambaBadPasswordCount sambaBadPasswordTime sambaPasswordHistory modifyTimestamp sambaLogonHours modifyTimestamp uidNumber gidNumber homeDirectory loginShell gecos 6927694-Oct 10 17:06:37 prosrvuiosmb151 slapd[13037]: conn=52 op=41 SEARCH RESULT tag=101 err=0 nentries=1 text= 6927695-Oct 10 17:06:37 prosrvuiosmb151 slapd[13037]: conn=52 op=42 SRCH base="dc=mydomain,dc=com,dc=ec" scope=2 deref=0 filter="(&(objectClass=sambaGroupMapping)(gidNumber=0))" 6927696-Oct 10 17:06:37 prosrvuiosmb151 slapd[13037]: conn=52 op=42 SRCH attr=gidNumber sambaSID sambaGroupType sambaSIDList description displayName cn objectClass 6927697-Oct 10 17:06:37 prosrvuiosmb151 slapd[13037]: conn=52 op=42 SEARCH RESULT tag=101 err=0 nentries=0 text= 6927698-Oct 10 17:06:37 prosrvuiosmb151 slapd[13037]: conn=52 op=43 SRCH base="dc=mydomain,dc=com,dc=ec" scope=2 deref=0 filter="(&(objectClass=sambaGroupMapping)(sambaSID=s-1-5-32-545))" 6927699-Oct 10 17:06:37 prosrvuiosmb151 slapd[13037]: conn=52 op=43 SRCH attr=gidNumber sambaSID sambaGroupType sambaSIDList description displayName cn objectClass I can log with users created with smbldap-tools, Juan Diego

TLS very strange behaviour
by Olivier 10 Oct '11

10 Oct '11

Hello, I have two ldap servers, my goal is to configure them in multimaster mode with an sasl authentication based on certificates. With the following configurations, that works well : ### slapd.conf for ldap1 : syncrepl rid=121 provider=ldap://ldap2.example.fr searchbase="dc=example,dc=fr" schemachecking=on type=refreshOnly interval=00:00:00:05 retry="10 +" bindmethod=sasl saslmech=external authcid="cn=replicator,ou=system,dc=example,dc=fr" authzid="dn:cn=replicator,ou=system,dc=example,dc=fr" tls_cert=/etc/openldap/cacerts/syncrepl.crt tls_key=/etc/openldap/cacerts/syncrepl.key tls_reqcert=demand mirrormode on ### slapd.conf for ldap1 : syncrepl rid=121 provider=ldap://ldap2.example.fr searchbase="dc=example,dc=fr" schemachecking=on type=refreshOnly interval=00:00:00:05 retry="10 +" bindmethod=sasl saslmech=external authcid="cn=replicator,ou=system,dc=example,dc=fr" authzid="dn:cn=replicator,ou=system,dc=example,dc=fr" tls_cert=/etc/openldap/cacerts/syncrepl.crt tls_key=/etc/openldap/cacerts/syncrepl.key tls_reqcert=demand mirrormode on # of course I have provided the CA certificate in both files. TLSCACertificateFile /etc/openldap/cacerts/CA.crt # I also configured properly acl for "replicator" # and have issued the right certificate -> No problem, it works. Now I also have configured certificates to be able to talk with the servers on TLS : ### slapd.conf for ldap1 : TLSCertificateFile /etc/openldap/cacerts/server1.crt TLSCertificateKeyFile /etc/openldap/cacerts/server1.key TLSCipherSuite HIGH ### slapd.conf for ldap2 : TLSCertificateFile /etc/openldap/cacerts/server2.crt TLSCertificateKeyFile /etc/openldap/cacerts/server2.key TLSCipherSuite HIGH That also works perfectly ( ldapsearch with -ZZ responds properly ) I therefore decided to try to starttls for synchronisation. I added in syncrepl for ldap1 : ## ldap1 syncrepl ... starttls=yes tls_cacert=/etc/openldap/cacerts/CA.crt ... And the synchronizations worked well, TLS being started when ldap1 is client. I then added the starttls directive on server ldap2 and removed it on server ldap1 : ## ldap2 syncrepl ... starttls=yes tls_cacert=/etc/openldap/cacerts/CA.crt ... The synchronization also worked well, TLS being started this time when ldap2 is client. HERE IS THE PROBLEM : II tried to starttls in bothe syncrepl directives on both servers ldap1 and ldap2, here is what I get : ldap1 # /usr/sbin/slapd -f slapd.conf -h ldap:/// -u ldap -d Sync ... TLS: error: accept - force handshake failure: errno 11 - moznss error -12273 TLS: can't accept: TLS error -12273:Unknown code ___P 15.

Any idea ? --- Olivier

Overlays: using search attributes
by Johan Jakus 10 Oct '11

10 Oct '11

Hello everyone, As mentioned before, I'm working on an overlay. And, I need to retrieve all the attributes send with the search request. Here is a part of my source: AttributeDescription* patt = op->oq_search.rs_attrs->an_desc; while(patt != NULL) { fprintf(fdebug, "attributes: %*s \n", (int) patt->ad_cname.bv_len, patt->ad_cname.bv_val); patt = patt->ad_next; } This only writes the name of the first attribute to the "fdebug" file. And the "patt->ad_next" is NULL (even when I've lots of attributes in my request). I tried using the AttributeName with the "an_name", but in the AttibuteName structure there is no pointer to the next AttibuteName. I could realy use some help! Thanks! Johan Jakus

State of the relay backend and rwm overlay, is it safe?
by Jeffrey Crawford 09 Oct '11

09 Oct '11

Hello, I'm sorry if this is answered somewhere already but I haven't found it. In short we need to re-map some attributes for specific replication schenerios where the replica actually records the data that we've mapped on the master server. Everything works as needed however I did notice that both relay and rwm have been tagged as experimental. This would be used in a production environment so I'm trying to get a sense if I can offer to use these features in our architechture. Or if these backends/overlays are not considered safe to use. I'm using openldap 2.4.26 Thanks Jeffrey

You also need to put your TLS certs into /var/ldap in NSS format (you can generate/convert them with certutil[1]) and edit /etc/pam.conf for LDAP authentication.

Best way to set up TLS certificates when using syncrepl?
by Bob Fitch 08 Oct '11

08 Oct '11

Hi, I'm trying to figure out the best way to create certificates for LDAPS on servers that replicate to each other. I'm not huge on PKI knowledge, so I'm not exactly sure if what I have is correct. I have two openldap servers that essentially look like this: serverA (provider) ----> serverB (consumer) serverA, serverB and all clients have "URI ldaps://serverA ldaps://serverB" in ldap.conf. I'm trying to make sure all clients can query both serverA and serverB via LDAPS - without extensive re-configuration of ldap.conf should serverA fail. In otherwords, I want the clients to just work, so it doesn't distract the Admin's from fixing serverA. I figured the best way to do this would be to create a single private key on serverA, and from that create certificates for serverA, serverB and any other client. serverB get's a copy of the single private key, just in case. serverA: olcTLSCACertificateFile: /path/to/certificate-authority.crt olcTLSCertificateKeyFile: /path/to/shared-key.key olcTLSCertificateFile: /path/to/serverA-certificate.crt ldap.conf: TLS_CACERT /path/to/certificate-authority.crt serverB: olcTLSCACertificateFile: /path/to/certificate-authority.crt olcTLSCertificateKeyFile: /path/to/shared-key.key olcTLSCertificateFile: /path/to/serverB-certificate.crt ldap.conf: TLS_CACERT /path/to/certificate-authority.crt Does this look correct, given that syncrepl needs to occur between serverA+serverB during normal operation, but LDAPS needs to function correctly between serverB+clients when serverA has failed? Thanks in advance, Bob.

Overlay memberof does not work with groupOfUniqueNames
by JOSE L MARTINEZ-AVIAL 08 Oct '11

08 Oct '11

Hi, I've an openldap 2.4.23 over RHEL4. I compilled it with the option to use overlay memberof, and it's been working well so far when I created groupOfNames. The issue is that I need to switch to groupOfUniqueNames instead of groupOfNames. When I do that, it seems that the overlay does not work, so I don't receive any group at all when I do a search returning memberof. Is it possible to setup the overlay to do that? Thank you Jose Luis
