When setting up LDAP Authentication in the Admin Console and a user clicks on ‘Test’, the configuration fails and the result is ‘Invalid Base DN’:
After setting the log4j.logger.org.springframework.security logger to DEBUG in appian_log4j.properties (located in <APPIAN_HOME>/ear/suite.ear/resources), the following error is printed in the application server log:
DEBUG org.springframework.security.ldap.authentication.BindAuthenticator - Retrieving attributes...
When testing the LDAP configuration in the Administration Console, Appian binds as the user currently logged in to Appian and then attempts to query the LDAP directory to retrieve attributes associated with that user. The configuration fails to query the directory or to retrieve the user’s attributes due to lack of privileges/permissions, which manifests through an ‘Invalid Base DN’.
This article applies to Appian 7.10 and later.
