The LDAP connector can be used with any directory which supports the LDAP and LDAPS protocols such as OpenLDAP, Active Directory or eDirectory.

Installing the connector

The steps below describe how to install and start the connector. Depending on whether you are using Kubernetes, Swarm or RPM, the instructions will vary.

RPM File

First, download jar file into /usr/local/openiam/connectors/bin and change owner to openiam user.

wget https://download.openiam.com/release/enterprise/4.2.1.4/connectors/ldap-connector-rabbitmq.jar
chown openiam:openiam /usr/local/openiam/connectors/bin/ldap-connector-rabbitmq.jar

Next, create new .sh file for starting ldap connector by running:

nano ldap_start.sh

Content of the file:

#!/bin/bash
. /usr/local/openiam/env.conf
export VAULT_CERTS="$HOME_DIR/vault/certs/"
export JAVA_HOME="$HOME_DIR/jdk"
export JAR_FILE="ldap-connector-rabbitmq"
export JAVA_OPTS="-Xmx256m -Djdk.tls.client.protocols=TLSv1.2"
su openiam -c "$JAVA_HOME/bin/java -Dlogging.level.root=ERROR -Dlogging.level.org.openiam=ERROR -Dconfpath=$HOME_DIR/ -Djavax.net.ssl.keyStorePassword=changeit -Djavax.net.ssl.trustStore=$HOME_DIR/conf/$JAR_FILE/ -jar $JAVA_OPTS $HOME_DIR/connectors/bin/$JAR_FILE.jar > $HOME_DIR/logs/$JAR_FILE.log&"

Make file executable by running:

chmod +x ldap_start.sh

To start the connector, use the following command:

./ldap_start.sh

Docker swarm

Kubernetes

Connector Troubleshooting Tips

1. SSL connection issue

Symptoms:

org.openiam.connector.core.base.exception.ConnectorException: javax.naming.CommunicationException: simple bind failed: xxxxx.xx.xxx.xxx.xxx:636 [Root exception is javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target] Caused by: javax.naming.CommunicationException: simple bind failed: myldap.example.com:636

Resolution:

1. make sure port is open and reachable, and you can connect via telnet command

telnet myldap.example.com 636

1. If you are connecting to LDAP via secured port 636 you should import ca_cert issued by domain into java keystore:

keytool -noprompt -import -v -trustcacerts -alias ldap_ca$(pwgen -s 13 1) -file /path/to/ca_cert.crt -keystore /usr/local/openiam/jdk/lib/security/cacerts -keypass changeit -storepass changeit

note that certificate must be imported into proper JVM that is used to start connector After you should restart connector.
