Re: Syncrepl partial replication based on attribute problem

by Jeffrey Crawford

Ok I think I got this to work I didn't add a filter to the syncrepl parameter so I'm using ACL's as before, however I changed the acls to allow the replica account access to the attributes entry and entryUUID only on every item in the directory, now setting attributes to values so that they no longer match the access to the rest of the acls seem to do what I wan't however I'm not quite sure how. so in short the provider looks something like this: olcAccess: to dn.subtree="dc=example,dc=org" attrs=entry,entryUUID by dn.base="cn=replica,ou=admins,dc=example,dc=org" ssf=128 read by * none break olcAccess: to dn.subtree="dc=example,dc=org" filter="(replicateMe=TRUE)" attrs=@inetOrgPerson,@posixAccount,entryCSN,contextCSN,createTimestamp,modifyTimestamp,structuralObjectClass by dn.base="cn=replica,ou=admins,dc=example,dc=org" ssf=128 read by * none break And the replicas are configured as so: dn: olcDatabase={1}hdb,cn=config changeType: modify replace: olcSyncrepl olcSyncrepl: rid=1 provider=ldap://ldap-!!!!ENV!!!!-1.example.org:1389/ starttls=critical tls_reqcert=never bindmethod=simple retry="60 10 900 92 86400 3" binddn="cn=replica,ou=admins,dc=example,dc=org" credentials=!!!!PW!!!! schemachecking=off searchbase="dc=example,dc=org" type=refreshAndPersist olcSyncrepl: rid=2 provider=ldap://ldap-!!!!ENV!!!!-2.example.org:1389/ starttls=critical tls_reqcert=never bindmethod=simple retry="60 10 900 92 86400 3" binddn="cn=replica,ou=admins,dc=example,dc=org" credentials=!!!!PW!!!! schemachecking=off searchbase="dc=example,dc=org" type=refreshAndPersist now the following will add a record to the replica: dn: uid=user,ou=people,dc=example,dc=org changeType: modify replace: replicateMe replicateMe: TRUE And the following will take it away (delete): dn: uid=user,ou=people,dc=example,dc=org changeType: modify replace: replicateMe replicateMe: FALSE However I don't know enough about the underlying code to be sure the following is working as designed. Meaning I don't want to be relying on a bug that might get fixed later.

It means that we should *not* design our replication based on ACL-filtering (which, unfortunately, we have done too), but, on the contrary, that we should design our DIT so that it can cover our replication needs based on consumer base/scope/filter configuration, and we should design/adapt our ACLs with the above rule in mind. >> >> Please confirm the above thoughts. >> >> Thanks, >> Nick > > > > > -- > I fly because it releases my mind from the tyranny of petty things . . . > > — Antoine de Saint-Exupéry > > Jeffrey E.

ldap_sasl_interactive_bind_s failed (-2) using openldap v2.3.43 when trying to replicate via syncrepl.

by Kristian Kostecky

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi guys, I have a configuration that consists of 3 ldap servers. One is the provider and there are 2 consumers. I am using syncrepl to do the synchronization. simple and anonymous binds are totally disabled and Kerberos must be used via SASL (GSSAPI) and TLS to connect to the LDAP server. distro: centos 5.4 openldap 2.3.43 cyrus-sasl 2.1.22 Other things: - - clocks are all in sync - - hostnames all have forward and reverse mappings and all dns servers in /etc/resolv.conf respond with proper entries on the consumer and both providers. Here's the catch, the two providers are configured the same (except for hostnames/ips) and the first one works perfect. What is really frustrating is the lack of logging that is available to tell me what the problem is. I've tried loglevel -1 and it gave me even less info in regards to the SASL authentication than leaving it off. The affected consumer is giving me: Mar 31 22:41:00 ZZZ slapd[2442]: slapd starting Mar 31 22:41:02 ZZZ slapd[2442]: do_syncrep1: rid 010 ldap_sasl_interactive_bind_s failed (-2) Mar 31 22:41:02 ZZZ slapd[2442]: do_syncrepl: rid 010 quitting On the "Provider": Mar 31 17:49:54 XXX slapd[3494]: conn=212 fd=21 ACCEPT from IP=10.130.1.230:60288 (IP=0.0.0.0:389) Mar 31 17:49:54 XXX slapd[3494]: conn=212 op=0 STARTTLS Mar 31 17:49:54 XXX slapd[3494]: conn=212 op=0 RESULT oid= err=0 text= Mar 31 17:49:54 XXX slapd[3494]: conn=212 fd=21 TLS established tls_ssf=256 ssf=256 Mar 31 17:49:54 XXX slapd[3494]: conn=212 op=1 UNBIND Mar 31 17:49:54 XXX slapd[3494]: conn=212 fd=21 closed This is what's REALLY weird - from the affected/broken box, ZZZ, after I kinit, I can do an LDAP search or ldapwhoami, no problems! So, kerberos and GSSAPI via SASL is working fine. ie: ldapsearch -H ldaps://XXX/ -Y GSSAPI -> will dump the entries. or ldapwhoami -H ldaps://XXX/ -Y GSSAPI -> shows me that proper creds If I destroy the credentials, it doesn't work as would be expected. ON the working consumer, the behaviour is that I can ldapsearch and ldapwhoami properly after I kinit and when I start ldap it will authenticate properly with the provider via SASL GSSAPI and replicates the DB. If I kdestroy the credentials and start it, I get the same error that I'm struggling with on the box that doesn't work ->ldap_sasl_interactive_bind_s failed (-2) This behaviour leads me to believe that for some reason the ldap server on the box that doesn't work is having problems transmitting the kerberos credentials to the provider, whereas the ldapsearch and ldapwhoami binaries are not having problems. There are some suspicious differences between the consumer that works and the broken one. The provider and consumer that works both have TLDs that match - '.com' and the consumer whose synrepl process won't authenticate is part of the .eu TLD. However, as you can see below in the krb5.conf files, the .com and .eu TLDS are always mapped to the same authentication realm. PLUS, again, ldapsearch and ldapwhoami WORK. It's just the syncrepl process that isn't quite getting the auth right. This is the provider's pertinent configs: slapd.conf: overlay syncprov syncprov-checkpoint 100 10 syncprov-sessionlog 100 This is the consumer's pertinent configs (WORKS ON one, not on the other) slapd.conf: syncrepl rid=10 provider=ldap://xxx.XXX.com starttls=yes type=refreshOnly interval=00:00:01:00 searchbase="dc=XXX,dc=com" schemachecking=off bindmethod=sasl saslmech=GSSAPI krb5.conf [same as provider and kerb server]: [libdefaults] default_realm = BOUNCE.AAA.COM encrypt = true allow_weak_crypto = false clockskew = 600 dns_lookup_realm = false dns_lookup_kdc = false ticket_lifetime = 8h forwardable = no proxiable = no [realms] BOUNCE.AAA.COM = { kdc = XXX.com kdc = YYY.com kdc = ZZZ.eu admin_server = XXX.com } [domain_realm] .com = BOUNCE.AAA.COM .eu = BOUNCE.AAA.COM All help is greatly appreciated!

Problems with syncrepl state

by Berthold Cogel

Hello, we have a cluster of LDAP servers consisting of one provider and 4 consumer. We're upgrading the os of the systems by proving an replacement system for each of the five systems. Then we stop the slapd on the system that should be replaced, dump the database with slapcat, copy it to new system, switch hostname and ip of both systems. We shut down the old and reboot the new system. Then we slapadd the database on the new system. So far so good... We started with the provider. After importing the database and starting the slapd on the new provider, we get errors for the syncrepl state on all consumer systems: "Can't get Context CSN with SID <x> from ldap+tls://localhost. Please set SID with -I option." We're using check_ldap_syncrepl_status from ltb-project with icinga2 to monitor the replication. I don't know how to fix this. When I modify an entry in the provider, it is synced to the consumer. But the status error stays. On all four consumers. I've then 'upgraded' a consumer by starting the slapd on the replacment system without any database. The system started the sync and after completion the error was gone. But syncing takes more time than importing a dump from a local file. And in a case where we have to rebuild the provider from scratch after a crash, it might be not an option to resync one consumer after the other to rebuild the complete cluster. Is there a method to fix the problem? Syncrepl configuration on the provider overlay syncprov syncprov-checkpoint 100 10 syncprov-sessionlog 100 Syncrepl configuration on the consumer syncrepl rid=<x> provider=ldap://yxz:389 binddn="cn=xxxxxxx" credentials="xxxxxxx" tls_cacertdir=/etc/pki/tls/certs tls_reqcert=demand bindmethod=simple starttls=critical searchbase="xxxxxx" type=refreshAndPersist retry="10 10 300 +" filter="(objectClass=*)" scope=sub attrs="*,+" sizelimit=unlimited timelimit=unlimited schemachecking=off Regards Berthold Cogel

That is not supported. You can only use multiple consumers in the same database if they are all pointing at different providers (and each of those providers uses a unique serverID). > whats happening with these consumers is that the initial sync seems to > work and some changes to the provider do make it down to the consumer > but lately most changes are NOT making it down to the consumer, when I > log sync then I am seeing that the csn is committed for the change for > the first rid but then for the next rid it logs that the csn is too old? -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

When I Check that the user can bind to AD: ldapsearch -x -H ldap://dc1.example.com/ \ -D cn=user,cn=Users,DC=ad,DC=example,DC=com \ -w userpassword \ -b cn=user,cn=Users,DC=ad,DC=example,DC=com \ Or with -s base \ "(objectclass=*)" Or testsaslauthd -u user -p userpassword It´s works. I was reading about and Seems don´t find the schemas of objectclass or userPassword attribute; But I could not resolve yet.

Syncrepl N-Way multimaster replication - Configuration issue on Rhel6

by coma

Hello everybody, i'm currently tring to configure N-Way multimaster replication, and i'm facing two issues with olcServerId and slapd -h options. For information: I'm running on Rhel6.6 with openldap 2.4.39-8. I'm running slapd on non-standard ports (11389 for ldap and ldap with TLS, and 11390 for ldaps) I've tried on standard ports but same issues. I've configured the replication following these two procedures: https://access.redhat.com/solutions/273533 http://www.openldap.org/doc/admin24/replication.html#N-Way%20Multi-Master - First Issue details: When i'm adding olcServerID's on both servers, using following ldif: cat <<EOF | ldapmodify -Y EXTERNAL -H ldapi:/// dn: cn=config changetype: modify replace: olcServerID olcServerID: 1 ldap://server1-test1.test.com olcServerID: 2 ldap://server2-test1.test.com EOF i'm no longer able to restart slapd. Error is: read_config: no serverID / URL match found. Check slapd -h arguments. To resolve it, i've tried to add the URL of my servers in correspondant /etc/sysconfig/ldapExample: SLAPD_LDAP=no SLAPD_LDAPI=yes SLAPD_LDAPS=no SLAPD_URLS="ldap://server1-test1.test.com:11389 ldaps://server1-test1.test.com:11390" But issue "Error is: read_config: no serverID / URL match found." is always present event after a server reboot and a full openldap reinstallationn. - Second issue détails (replication disabled, serverID's removed): With /etc/sysconfig/ldap configured as: SLAPD_LDAP=no SLAPD_LDAPI=yes SLAPD_LDAPS=no SLAPD_URLS="ldap://:11389 ldaps://:11390" i'm able to connect on port 11389/11390 with clear, starttls and SSL using a ldap browser or ldapsearch, But with /etc/sysconfig/ldap configured as: SLAPD_LDAP=no SLAPD_LDAPI=yes SLAPD_LDAPS=no SLAPD_URLS="ldap://server1-test1.test.com:11389 ldaps://server1-test1.test.com:11390" i'm not able to connect anymore. Can you please help me on this? Thanks in advance,
