ldap_solr

Apache solr doesn't implictly provide support for ldap authentication. Provided BasicAuthPlugin.java file enables the solr to work with ldap authentication as well.

Notes: these changes will enable ldap authentication along with basic authentication in solr. It doesn't disable basic authentication.

Steps to compile & configure solr are as followed:

Compile solr with changes:

1. Download the solr source code: https://github.com/apache/lucene-solr/tree/releases/lucene-solr/7.1.0

2. Unzip it & goto following path: lucene-solr-releases-lucene-solr-7.1.0\solr\core\src\java\org\apache\solr\security\

3. Replace the BasicAuthPlugin.java file with provided one.

4. Goto lucene-solr-releases-lucene-solr-7.1.0\solr\core directory & compile: $ ant compile

5. Once compilation is finished. Make jar: $ ant dist

6. Updated jar file would be present inside: lucene-solr-releases-lucene-solr-7.1.0\solr\build\solr-core\

Configure Solr with changes:

1. Enable basic authentication on solr. (follow solr guidelines)
2. Add these 3 lines in security.json file below "blockUnknown":true, as shown:

   "blockUnknown":true,
 
   "ldapURL":"127.0.0.1:10389/",
 
   "ldapBase":"o=sevenSeas",
 
   "ldapObjectClass":"inetOrgPerson",

Note: replace with appropriate ldap server parameters.

3. update security.json file in solr (follow solr guidelines).

4. Stop solr

5. Upload the solr-core jar file created earlier to following path in solr setup: /opt/solr/server/solr-webapp/webapp/WEB-INF/lib/

6. Replace the original jar with new one: $ mv solr-core-7.1.0-SNAPSHOT.jar solr-core-7.1.0.jar

7. start solr

8. access the solr gui with ldap users. Voila.
