Configuring the class file on Docker and Podman

Use a custom Java class file to transform your searches for LDAP for the community pod.

You must have already created and compiled the class file using Java 1.8.

The Docker and Podman commands are similar. The only difference is that docker precedes the command when issued in a Docker environment and podman precedes the name in a Podman environment. Example commands used in the Sametime documentation are shown using Docker. For Podman, change docker to podman.

To configure a custom Java class file to transform your searches for LDAP for the Sametime server on Docker you need to complete the following tasks.

Override the default LDAP settings to use the class file
Name the compiled class file StLdapCustomizedAttributes.classfile.
Place the StLdapCustomizedAttributes.classfile into the Sametime installation directory or a sub directory, example: ldap-custom-filter.
Identify the chat-server container ID by running the docker container ls command and finding the chat-server IMAGE. The NAME is the container name. For example: sametime-community-1.
Pull a copy of the StCommunityConfig.xml from the chat-servercontainer by running the following command, where containerid is the container name for the chat server identified in step 2.

If the StCommunityConfig.xml has already been copied and edited previously for a different setting, skip this step and edit the existingStCommunityConfig.xml.
```
docker cp <container_name>:/local/notesdata/StCommunityConfig.xml . 
```

Update the configuration that pertains to your custom Java class. Open theStCommunityConfig.xml file that was copied from the chat-server contain and edit the <LDAP> section as it pertains to your configuration.

The changes depend on what you are modifying, refer to the following table for guidance.

Type of change	Parameter name	What to specify	Example
Search filter for resolving person names	PersonResolveFilter	classname.methodname() for your custom code	`StLdapCustomized.peopleResolveFilter()`
Search filter for resolving group names	GroupResolveFilter	Class name and method name for a group filter, using the following format: `Classname.methodname()`	`StLdapCustomized.groupsResolveFilter()`.
Attribute of the person entry that defines the person's name	DescAttribute	Class name and method name for the formatting, with the name of the attribute inside, for example: Classname.methodname(attribute_name)	`StLdapCustomizedAttributes.displayName(cn)`

Save and close the StCommunityConfig.xmlfile.
Edit the docker-compose.yml file and add the following under the community section:
```
volumes: 
 - ./ StLdapCustomizedAttributes.class:/local/notesdata/java/ StLdapCustomizedAttributes.class
```
If the class files is placed in a sub-directory, it must be specified in the above volume path.
Start the Sametime server to apply the changes.
```
docker compose up -d
```
