LdapExtLoginModule authentication fails when some part of DN is part of LDAP URL -------------------------------------------------------------------------------- Key: WFLY-6534 URL: https://issues.jboss.org/browse/WFLY-6534 Project: WildFly Issue Type: Bug Components: Security Affects Versions: 10.0.0.Final Reporter: Ondrej Lukas In case when part of DN is placed in LDAP URL instead of baseCtxDN then authentication fails (see [1] for details about this URL) in LdapExtLoginModule. 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.
