Juraj Duráni created TEIID-4183: ----------------------------------- Summary: MSSQL JDBC driver invalidates kerberos ticket on Connection.close() Key: TEIID-4183 URL: https://issues.jboss.org/browse/TEIID-4183 Project: Teiid Issue Type: Bug Affects Versions: 8.7.5.6_2, 8.12.x Reporter: Juraj Duráni Assignee: Ramesh Reddy MSSQL JDBC driver invalidate kerberos ticket on Connection.close() (related bugzilla \[1\]). If user creates kerberos connection, driver invalidates ticket on closing connection (Connection.close()). Therefore ticket cannot be re-used. EAP team creates a workaround for this by adding module option *wrapGSSCredential=true* with additional setting *credentialLifetime=-1* \[2, 3, 4, 5\]. This works for static kerberos authentication. However, passthrough authentication (org.teiid.jboss.PassthroughIdentityLoginModule) does not work, because passed ticket is not managed by EAP but by client. \[1\] https://bugzilla.redhat.com/show_bug.cgi?id=1097276 \[2\] https://bugzilla.redhat.com/show_bug.cgi?id=1097276#c58 \[3\] https://issues.jboss.org/browse/SECURITY-905 \[4\] https://issues.jboss.org/browse/JBEAP-843 \[5\] https://github.com/wildfly-security/jboss-negotiation/commit/0c7e06f58a79... -- This message was sent by Atlassian JIRA (v6.4.11#64026)
