LdapLoginModule authentication fails when some part of DN is part of LDAP URL ----------------------------------------------------------------------------- Key: WFLY-6535 URL: https://issues.jboss.org/browse/WFLY-6535 Project: WildFly Issue Type: Bug Components: Security Affects Versions: 10.0.0.Final Reporter: Ondrej Lukas Assignee: Darran Lofthouse Priority: Major In case when part of DN is placed in LDAP URL instead of principalDNSuffix then authentication fails (see [1] for details about this URL) in LdapLoginModule. Authentication is provided by binding with user DN and password, but in this case user DN does not include DN part from LDAP URL which leads to fail.
