Out of curiosity, have you tried to wireshark the ldap connection to see what the servers are saying?
Or, if you're lucky enough to be pointing against eDirectory, an ndstrace on the ldap server will provide a lot of details about what it's doing and seeing as well. >>> Tadeusz Sacilowski <[email protected]> 04/21/15 9:52 PM >>> Hello, We are in the process of updating our CAS to version 3.5.3 using an LDAP (not LDAPS at the moment) for attributes. The current setup is two CAS nodes behind an f5 LTM for load balancing, using the Ehcache distributed ticket registry. All seems to be working ok for the most part except that we get the following intermittent login error: :org.springframework.ldap.CommunicationException: Connection reset; nested exception is javax.naming.CommunicationException: Connection reset [Root exception is java.net.SocketException: Connection reset]; remaining name 'ou=People,o=cp' Here are the first several lines from the trace in the CAS log: ERROR [org.jasig.cas.authentication.AuthenticationManagerImpl] - org.jasig.cas.adaptors.ldap.BindLdapAuthenticationHandler threw error authenticating [username: teststudent] org.springframework.ldap.CommunicationException: Connection reset; nested exception is javax.naming.CommunicationException: Connection reset [Root exception is java.net.SocketException: Connection reset]; remaining name 'ou=People,o=cp' at org.springframework.ldap.support.LdapUtils.convertLdapException(LdapUtils.java:100) at org.springframework.ldap.core.LdapTemplate.search(LdapTemplate.java:318) at org.springframework.ldap.core.LdapTemplate.search(LdapTemplate.java:360) at org.jasig.cas.adaptors.ldap.BindLdapAuthenticationHandler.authenticateUsernamePasswordInternal(BindLdapAuthenticationHandler.java:90) at org.jasig.cas.authentication.handler.support.AbstractUsernamePasswordAuthenticationHandler.doAuthentication(AbstractUsernamePasswordAuthenticationHandler.java:71) at org.jasig.cas.authentication.handler.support.AbstractPreAndPostProcessingAuthenticationHandler.authenticate_aroundBody2(AbstractPreAndPostProcessingAuthenticationHandler.java:85) I've seen some related post here but haven't found any documented resolutions. Any suggestions on how to troubleshoot this?
