Hello, I’ve got two 2.4.28 boxes and I’m trying to get two-way multimaster replication set up – first for cn=config, and then for the entire tree. I can attach more of config.ldif if needed, but here are what I think are the relevant snippets: First thing that leaps out is, of course, the certificate is for ds.clarku.edu and the hosts are called animal.clarku.edu and zoot.clarku.edu; that’s needed because I intend to round-robin those two hosts. I have TLS_REQCERT never in ldap.conf on each machine and I can do a successful “ldapsearch -H ldaps://animal.clarku.edu -x -D "cn=config" -W -b cn=config” from each machine to the other. dn: cn=config objectClass: olcGlobal cn: config olcAllows: bind_v2 olcArgsFile: /var/run/openldap/slapd.args olcAttributeOptions: lang- olcAuthzPolicy: none olcConcurrency: 25 olcConfigDir: /etc/openldap/ldap/slapd.d olcConfigFile: /etc/openldap/slapd.conf olcConnMaxPending: 400 olcConnMaxPendingAuth: 1000 olcGentleHUP: FALSE olcIdleTimeout: 0 olcIndexIntLen: 4 olcIndexSubstrAnyLen: 4 olcIndexSubstrAnyStep: 2 olcIndexSubstrIfMaxLen: 4 olcIndexSubstrIfMinLen: 2 olcLocalSSF: 71 olcLogLevel: stats sync olcPidFile: /var/run/openldap/slapd.pid olcReadOnly: FALSE olcReverseLookup: FALSE olcServerID: 1 ldaps://animal.clarku.edu olcServerID: 2 ldaps://zoot.clarku.edu olcSockbufMaxIncoming: 262143 olcSockbufMaxIncomingAuth: 16777215 olcThreads: 25 olcTLSCACertificatePath: /etc/openldap/nssdb olcTLSCertificateFile: ds.clarku.edu olcTLSVerifyClient: never olcToolThreads: 1 olcWriteTimeout: 0 dn: olcDatabase={0}config,cn=config objectClass: olcDatabaseConfig olcDatabase: {0}config olcAccess: {0}to * by * none olcAddContentAcl: TRUE olcLastMod: TRUE olcMaxDerefDepth: 15 olcMirrorMode: TRUE olcMonitoring: FALSE olcReadOnly: FALSE olcRootDN: cn=config olcRootPW: {SSHA}<PASSWORD> olcSyncrepl: {0}rid=001 provider=ldaps://animal.clarku.edu binddn="cn=config " bindmethod="simple" credentials="<PASSWORD>" searchbase="cn=config" type= refreshAndPersist retry="5 5 300 5" timeout=1 olcSyncrepl: {1}rid=002 provider=ldaps://zoot.clarku.edu binddn="cn=config" bindmethod="simple" credentials="<PASSWORD>” searchbase="cn=config" type=r efreshAndPersist retry="5 5 300 5" timeout=1 Here’s the –d1 output: 4f2ae081 do_syncrepl: rid=001 rc -1 retrying (4 retries left) 4f2ae081 slap_listener_activate(9): 4f2ae081 >>> slap_listener(ldaps:///) 4f2ae081 connection_get(15): got connid=1000 4f2ae081 connection_read(15): checking for input on id=1000 TLS: using moznss security dir /etc/openldap/nssdb prefix .
