I can connect to the master without issue using the command below: ldapsearch -LLL -x -H ldap://pdc.ldap.com:389 -D "cn=Replicator,ou=DSA,dc=my,dc=domain,dc=com" -s base -b "dc=my,dc=domain,dc=com" -w mypassword This is what I got from the log: init_sam_from_ldap: Entry found for user: i_test5 init_sam_from_ldap: no sambaSID or sambaSID attribute found for this user i_test5 ldapsam_getsampwnam: init_sam_from_ldap failed for user 'i_test5'! Username not found! Everytime I make any changes on an account using "pdbedit" using the master, the account is not found on the slave even if it was there before I made the change. Has anyone seen this before. I am migrating from slurpd to syncrepl. Openldap 2.3.43 Samba 3.0.33 Gentoo Linux Thanks in advance. -Ivan

Re: 2.4.22 mirrormode syncrepl credential password encryption

by Gémes Géza

Hi, Although I use cn=config instead of slapd.conf, my setup is similar. I've created one user (e.g. cn=replicator) with global read access. Created a certificate (and private key) for that user and mapped it to the user via: olcAuthzRegexp: {0}"cn=certificate data comes here" "cn=replicator" then my replica line looks like this: olcSyncrepl: {0}rid=001 provider=ldap://firstserver bindmethod=sasl saslmech=external authcid="cn=certificate data comes here" starttls=critical tls_cert=/path/to/the/cert tls_key=/path/to/the/privatekey tls_cacert=/path/to/the/cacert tls_reqcert=demand searchbase= "dc=example,dc=com" type=refreshAndPersist retry="5 5 300 5" timeout=1 > Hi, > > I have version 2.4.22 running with mirrormode enabled and it is > working well. > > I have a question regarding the credentials field in the syncrepl part > in slapd.conf. > > Must this be cleartext or can it be encrypted and what is considered > good practise > regarding which binddn to use.

Re: issues configuring SASL EXTERNAL and proxyauth with chain used for ppolicy_forward_updates

I want to replace GSSAPI with certificate-based (SASL EXTERNAL) authentication along with proxy authorization. Basically, I want to configure the equivalent of the following command line: > > LDAPTLS_KEY=server.key LDAPTLS_CERT=server.crt \ > ldapmodify -Z -Y EXTERNAL \ > -e '!authzid=dn:cn=proxydn,dc=example,dc=com' -e relax \ > -h ldap-master.example.com -f update_pwdfailuretime.ldif > > The command line works as expected -- it authenticates successfully using the server certificate, and then does PROXYAUTHZ to cn=proxydn,dc=example,dc=com to perform the modify operation. The issue is when I try to configure this behavior with chain on the consumer server.

Otherwise, any suggestions on the best way to troubleshoot this further would be great. Here’s a snippet from an ansible template we use for one of our tests: ```conf overlay chain chain-uri "{{ hostvars[providers | first].ldap_url }}" chain-tls start tls_cacert="{{ cacert_path }}" tls_cert="{{ config_path }}/{{ inventory_hostname }}.crt" tls_key="{{ config_path }}/{{ inventory_hostname }}.pem" tls_reqcert=demand chain-idassert-bind mode=legacy bindmethod=sasl saslmech=external binddn=cn=notused starttls=yes tls_cacert="{{ cacert_path }}" tls_cert="{{ config_path }}/{{ inventory_hostname }}.crt" tls_key="{{ config_path }}/{{ inventory_hostname }}.pem" tls_reqcert=demand ``` Other important items is the service account used as proxy must have: ```ldif … sn: service account authzTo: ldap:///ou=People,dc=example,dc=com??subtree?(objectclass=someperson) ``` Also, on the consumer: ```conf authz-regexp "cn=([^,]*),ou=Symas,o=Symas corp,l=Grand Junction,st=Colorado,c=us" "cn=$1,ou=clients,dc=example,dc=com" ``` And on the target: ```conf authz-policy to authz-regexp "cn=([^,]*),ou=Symas,o=Symas corp,l=Grand Junction,st=Colorado,c=us" "cn=$1,ou=servers,dc=example,dc=com" ``` HTH — Shawn

If set that variable in the ldap.conf everything works fine. But shouldn't the above function as an override to the default of 'demand'? The behaviour is the same when I change the above to use SSL instead. I think you're running into an issue that I reported in September 2010. See http://www.openldap.org/lists/openldap-technical/201009/msg00073.html and http://www.openldap.org/its/index.cgi?findid=6642 According to the Release Change Log, this issue should have been fixed in release 2.4.24. So you should definitely update to a more recent release. Best regards, Manuel
