Connect2id server requirements

2+ GBytes of system RAM
If you expect to service more than 100 thousand users the server will benefit from extra available memory.
Java 8
Make sure your Java is up to date with the latest security patches.
The server needs a database to persist its data, such as a client registrations and sticky grants. MySQL, PostgreSQL, H2, LDAP, DynamoDB and Redis are supported.
Java Servlet 3.0 Container
An Apache Tomcat web server is included in the download package. Other servlet v3.0+ containers are also supported.


Step 1.

Unzip the downloaded Connect2id server package in a suitable folder on your computer.

Step 2.

Start the Apache Tomcat web server, which has preinstalled and configured instances of the Connect2id server and an H2 database for persisting its data, the Connect2id login page (built with JavaScript), an LdapAuth web service for authenticating users against an included in-memory LDAP directory, and an OpenID Connect client.
