- | ===== Why use a remote connector server? ===== | + | Remote connector server is a standalone daemon used for interfacing some of the more difficult systems. You deploy connector bundles into the connector server. Then, you configure CzechIdM to use connectors from within the remote connector server. As far as IdM is concerned, there is no difference if actions on end system are performed by connector server or IdM itself. The only difference is in the point of origin of network communication. |

+ | ===== Why use remote connector server? ===== | ||
+ | |||
+ | CzechIdM | ||
+ | |||
+ | * We cannot run Java code on the target system (e. g. .NET code is needed). | ||
+ | * The OS does not have some normal API (e. g. old Windows without WinRM) so we need to run commands on it locally. | ||
+ | * Security reasons - we do not want to run the connector code under the same user as the CzechIdM. | ||
+ | * You need to use two different versions of one connector (or two connectors | ||
+ | |||
+ | ===== How does a remote connector server work in CzechIdM? ===== | ||
+ | |||
+ | The remote server connector configuration form behaves just like the local connector form - this means that definition is stored in the EAV attributes for system which it belongs to. System name, connector name and connector version are the key to EAV attributes in the CzechIdM. It is therefore possible to have multiple connectors with different versions in one remote connector server. | ||
+ | |||
+ | ===== Connector server setup ===== | ||
+ | |||
+ | ==== Obtaining connector server ==== | ||
+ | |||
+ | | ||
+ | |||
+ | < | ||
+ | |||
+ | - Download connector server from the [[https:// | ||
+ | - **Use version 1.4.5.1** of remote connector server and version **1.4.3.0** | ||
+ | - Download following libraries and add them to the '' | ||
+ | * jackson-annotations-2.9.8 | ||
+ | * jackson-core-2.9.8 | ||
+ | * jackson-databind-2.9.8 | ||
+ | - Add those libraries to the '' | ||
+ | |||
+ | </ | ||
+ | |||
+ | ==== Remote connector server configuration - Linux ==== | ||
+ | |||
+ | - Install Java 11 (OpenJDK headless is preferred). | ||
+ | - Create new OS user the connector server will run under. By default, we create user '' | ||
+ | |||
+ | < | ||
+ | useradd -b /opt -m -s /bin/bash connector-server | ||
+ | chmod 750 / | ||
+ | |||
+ | </ | ||
+ | |||
+ | - Copy over the connector server and unpack it. | ||
+ | |||
+ | < | ||
+ | cp connector-server-master.tar.gz / | ||
+ | chown connector-server: | ||
+ | su - connector-server | ||
+ | cd / | ||
+ | tar xzf connector-server-master.tar.gz | ||
+ | rm connector-server-master.tar.gz | ||
+ | |||
+ | </ | ||
+ | |||
+ | - Correct directory permissions: | ||
+ | |||
+ | < | ||
+ | cd / | ||
+ | chmod 750 bin/ bundles/ certs/ conf/ lib/ logs/ scripts/ | ||
+ | |||
+ | </ | ||
+ | |||
+ | - Your setup should look like this: | ||
+ | |||
+ | < | ||
+ | ls -l / | ||
+ | total 4 | ||
+ | drwxrwxr-x 9 connector-server connector-server 4096 Oct 10 16:45 connid-connector-server | ||
+ | |||
+ | ls -l / | ||
+ | total 23448 | ||
+ | drwxr-x--- 5 connector-server connector-server | ||
+ | drwxr-x--- 2 connector-server connector-server | ||
+ | drwxr-x--- 2 connector-server connector-server | ||
+ | drwxr-x--- 2 connector-server connector-server | ||
+ | -rw-rw-r-- 1 connector-server connector-server 11976830 Oct 10 16:45 datetime | ||
+ | drwxr-x--- 3 connector-server connector-server | ||
+ | -rw-rw-r-- 1 connector-server connector-server | ||
+ | drwxr-x--- 2 connector-server connector-server | ||
+ | drwxr-x--- 3 connector-server connector-server | ||
+ | -rw-rw-r-- 1 connector-server connector-server 11976825 Oct 10 16:45 sys | ||
+ | |||
+ | </ | ||
+ | |||
+ | - Set executable permission on the main script. | ||
+ | |||
+ | < | ||
+ | cd connid-connector-server | ||
+ | chmod +x bin/ | ||
+ | |||
+ | </ | ||
+ | |||
+ | - Create strong password for the connector server (use '' | ||
+ | |||
+ | < | ||
+ | ./ | ||
+ | |||
+ | </ | ||
+ | |||
+ | - If you plan to connect to remote connector server remotely (not locally on '' | ||
+ | - As root, create systemd unit ''/ | ||
+ | |||
+ | <file txt connector-server.service> | ||
+ | [Unit] | ||
+ | Description=Java Connector Server Service | ||
+ | After=network-online.target | ||
+ | |||
+ | [Service] | ||
+ | User=connector-server | ||
+ | WorkingDirectory=/ | ||
+ | ExecStart=/ | ||
+ | SuccessExitStatus=143 | ||
+ | |||
+ | [Install] | ||
+ | WantedBy=multi-user.target | ||
+ | |||
+ | |||
+ | </ | ||
+ | |||
+ | - Reload systemd, start and enable the connector server. | ||
+ | |||
+ | < | ||
+ | systemctl daemon-reload | ||
+ | systemctl start connector-server | ||
+ | systemctl enable connector-server | ||
+ | |||
+ | </ | ||
+ | |||
+ | - For additional configuration, | ||
+ | - Connector server is now configured. You can deploy connector bundles into it. You have to restart the connector server for changes to take effect. | ||
+ | - Add connector bundles ('' | ||
+ | - Add custom scripts the CzechIdM will use under the '' | ||
+ | - Add certificates to be used under '' | ||
+ | |||
+ | === Configuring log rotation === | ||
+ | |||
+ | The principle of rotating logs on Linux is the same as for the CzechIdM. Just create a proper logrotate file ''/ | ||
+ | |||
+ | < | ||
+ | / | ||
+ | rotate 90 | ||
+ | daily | ||
+ | dateext | ||
+ | copytruncate | ||
+ | missingok | ||
+ | notifempty | ||
+ | compress | ||
+ | } | ||
+ | |||
+ | </ | ||
+ | |||
+ | === Configuring SSL truststore === | ||
+ | |||
+ | When you interface end systems remotely, you **have to** secure the communication with TLS. For this to work, you need a Java truststore. This short howto will show you how to create one. | ||
+ | |||
+ | - Get (or create - as we do there) a certificate of the end system. | ||
+ | |||
+ | < | ||
+ | su - connector-server | ||
+ | cd / | ||
+ | openssl genrsa -out fakecert.key | ||
+ | openssl req -new -key fakecert.key -out fakecert.csr -subj "/ | ||
+ | openssl x509 -req -in fakecert.csr -signkey fakecert.key -days 1 -sha256 -out fakecert.crt | ||
+ | |||
+ | </ | ||
+ | |||
+ | - Import the certificate into the truststore. If the '' | ||
+ | |||
+ | < | ||
+ | keytool -importcert -file fakecert.crt -alias placeholder-cert -keystore truststore.jks | ||
+ | Enter keystore password: | ||
+ | Re-enter new password: | ||
+ | ... | ||
+ | Trust this certificate? | ||
+ | Certificate was added to keystore | ||
+ | |||
+ | </ | ||
+ | |||
+ | - Just some cleanup. | ||
+ | |||
+ | < | ||
+ | rm fakecert.key fakecert.csr fakecert.crt | ||
+ | chmod 644 truststore.jks | ||
+ | # the connector server user should not be able to write the truststore, only read it | ||
+ | chown root: | ||
+ | |||
+ | </ | ||
+ | |||
+ | - Add truststore to startup script '' | ||
+ | |||
+ | < | ||
+ | cd / | ||
+ | vim bin/ | ||
+ | |||
+ | # add this snippet to the command line that executes the connector server | ||
+ | -Djavax.net.ssl.trustStore=/ | ||
+ | |||
+ | </ | ||
+ | |||
+ | - Restart the connector server. | ||
+ | |||
+ | |||
+ | ==== Remote connector server configuration - Windows ==== | ||
+ | |||
+ | 1) Install Java 1.8 (OpenJDK headless is preferred). | ||
+ | |||
+ | <note important> | ||
+ | |||
+ | 2) Unpack connector server to his root directory " | ||
+ | |||
+ | 3) Create trustore for connector server. Use git bash in direcotory " | ||
+ | |||
+ | * Get (or create - as we do there) a certificate of the end system. | ||
+ | |||
+ | < | ||
+ | openssl genrsa -out fakecert.key | ||
+ | openssl req -new -key fakecert.key -out fakecert.csr -subj "/ | ||
+ | openssl x509 -req -in fakecert.csr -signkey fakecert.key -days 1 -sha256 -out fakecert.crt | ||
+ | |||
+ | </ | ||
+ | |||
+ | * Import the certificate into the truststore. If the truststore.jks does not exist, the keytool will create it. | ||
+ | |||
+ | < | ||
+ | /c/Program\ Files/ | ||
+ | Enter keystore password: | ||
+ | Re-enter new password: | ||
+ | ... | ||
+ | Trust this certificate? | ||
+ | Certificate was added to keystore | ||
+ | |||
+ | </ | ||
+ | |||
+ | * Just some cleanup. | ||
+ | |||
+ | < | ||
+ | rm fakecert.key fakecert.csr fakecert.crt | ||
+ | |||
+ | </ | ||
+ | |||
+ | 4) Add trustore location and password to service installation in „bin\ConnectorServer.bat“(windows). These parameters are in script already, so just trustore path and password. | ||
+ | |||
+ | < | ||
+ | " | ||
+ | |||
+ | </ | ||
+ | |||
+ | 5) Start CMD under system admin. Then go to connector-server root directory. | ||
+ | |||
+ | < | ||
+ | cd C: | ||
+ | bin\ConnectorServer.bat /setkey | ||
+ | |||
+ | </ | ||
+ | |||
+ | <note important> | ||
+ | |||
+ | 6) Add connectors to " | ||
+ | |||
+ | 7) Then setup connector-server key and install windows service(connector_server). | ||
+ | |||
+ | < | ||
+ | bin\ConnectorServer.bat /install connector_server | ||
+ | |||
+ | </ | ||
+ | |||
+ | 8) Then start service in " | ||

It is necessary to supply the host and port on which the connector is available on remote server. If the server is secured by password, you will need to fill in the password in order to successfully connect to the remote connector server. Password will be stored in local confidential storage. | ||

+ | |||
+ | <note tip>If you change the key (password) of the remote connector server, you must change the key also in the remote connector server configuration in IdM. You may need to restart IdM (i.e. the application server Tomcat) to force the IdM to start using the new key. Otherwise, you would get this exception when testing the connection: | ||
