As of version 5.0.0, the UnboundID LDAP SDK for Java is available under the terms of the Apache License, Version 2.0, which is a very permissive OSI-approved open source license. This is the recommended license for all new uses of the LDAP SDK. More information about the terms of the Apache License, Version 2.0, as well as the full text of the license, is provided below.
Versions of the LDAP SDK prior to 5.0.0 were available under three other licenses:
- The OSI-approved GNU General Public License version 2 (GPLv2).
- The OSI-approved GNU Lesser General Public License version 2.1 (LGPLv2.1)
- The not-open-source-but-still-free-to-use UnboundID Free Use License
The LDAP SDK is still available to use under the terms of these licenses for backward compatibility (or if you simply prefer them over the Apache License for some reason).
Further, licensees of Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 server products may also use the LDAP SDK under the terms of the server product licenses.
The Apache License, Version 2.0 is very permissive, and it should be possible to use the LDAP SDK under the terms of this license in just about any application, whether open source or proprietary, and whether free or paid. You can use it privately, and you are free to distribute the LDAP SDK in source and/or compiled form, either on its own as part of a larger work. If any of the software is covered by patents, then you are granted the right to use those patents in the context of the LDAP SDK.
The main requirements when using the LDAP SDK under the terms of the Apache License, Version 2.0 are as follows:
-
You are required to include the text of the full license (as provided below, or online at https://www.apache.org/licenses/LICENSE-2.0) with your application.
-
You are not required to provide source code for the LDAP SDK, even if you make changes to it. However, if you do distribute the source code for the LDAP SDK, then you are not permitted not remove any existing copyright notices. If you distribute a modified version of the LDAP SDK source code, then you need to indicate what changes you made to it.
-
You cannot hold Ping Identity Corporation or any developers liable for any defects or other problems found with the software.
-
You are not permitted to use any Ping Identity or UnboundID trademarks. You can say that your application uses the UnboundID LDAP SDK for Java as developed by Ping Identity Corporation, and if you distribute a modified version, then you can say that it is based on the UnboundID LDAP SDK for Java as developed by Ping Identity Corporation, but you can't use UnboundID or Ping Identity in the name of your modified version.
