[jboss-jira] [JBoss JIRA] (SECURITY-933) The root cause of login module failures gets lost when multiple login modules are stacked

The root cause of login module failures gets lost when multiple login modules are stacked ----------------------------------------------------------------------------------------- Key: SECURITY-933 URL: https://issues.jboss.org/browse/SECURITY-933 Project: PicketBox Issue Type: Bug Components: Negotiation Reporter: Tomas Hofman Assignee: Tomas Hofman Fix For: Negotiation_3_0_1_CR1 https://bugzilla.redhat.com/show_bug.cgi?id=1288668 The root cause of login module failures gets lost when multiple login modules are stacked and the "flag" attribute is set to "optional". When the login attempt fails (invalid bindCredential on the LdapExtLoginModule for example) the authentication request will continue to the next login module in the stack. In this situation, the exceptions "cause" attribute is getting overwritten during the processing of the other login modules. This results in the actual cause to get lost during processing. This makes troubleshooting authentication failures difficult.
