Pinned topic WAS(8.5) + Spring Security: Using an LDAP Authentication Provider
I have tested this simple tutorial "Spring Security - MVC: Using an LDAP Authentication Provider":
I am able to run it successfully at Tomcat, Glassfish, even at WAS8.5 Liberty Profile. But when I run it at the full WAS profile, I experience the following exception:
java.lang.ClassCastException: com.sun.jndi.ldap.LdapCtx incompatible with org.springframework.ldap.core.DirContextAdapter
After the surfing at Internet, I tried the following:
In the Administrative Console,
Server-specific Application Settings -> Classloader policy I set up: Single.
Server-specific Application Settings -> Class loading mode: I tried both options - "Classes loaded with parent class loader first" as well as "Classes loaded with local class loader first (parent last)"
I have restarted server after each change.
I found a recommendation to set up a custom property
com.ibm.ws.webcontainer.invokefilterscompatibility = true
in the Administrative Console -> Application servers -> my server -> Web container -> Customer properties.
Nothing from the above helped.
I have noticed, that when I see into the Class loader viewer, the class com.sun.jndi.ldap.LdapCtxFactory is loaded by two classloaders:
1) Extension - com.ibm.ws.bootstrap.ExtClassLoader
and also by
2) Module - com.ibm.ws.classloader.CompoundClassLoader
I guess, that the above information could help to solve the problem.
Thanks for the hint how to step forward.

Re: WAS(8.5) + Spring Security: Using an LDAP Authentication Provider2013-01-08T08:08:18Z in response to SystemAdminUnfortunately I did not find the solution. Fortunately (for me only and I know that just temporarily), it was just a test, I did not need it immediately - so I put it away.

Re: WAS(8.5) + Spring Security: Using an LDAP Authentication Provider2013-03-13T09:04:27Z in response to SystemAdminI am using Websphere Application Server 188.8.131.52 and I am facing exactly the same problem:
22.2.2013 8:41:58:397 EET00000087 webapp E com.ibm.ws.webcontainer.webapp.WebApp logServletError SRVE0293E: [S
ervlet Error]-ServletNameNotFound: java.lang.ClassCastException: com.sun.jndi.ldap.LdapCtx incompatible with org.sprin
Does anyone know a workaround for this, or whether it will be fixed in SP 2 ?
Seems that the same LDAP problem with spring security has been also in WAS 8.0 but it has been fixed in 184.108.40.206.
I also found this workaround, but I dont think it's a good option to write all the ldap code again from scratch.
Has anyone managed to get the Spring Security LDAP stuff working in WAS 8.5 ?
Re: WAS(8.5) + Spring Security: Using an LDAP Authentication Provider2013-03-13T13:27:47Z in response to SystemAdminHi, It sounds like you have something that works on V220.127.116.11 and not V18.104.22.168 so I think opening a PMR for the service team to look at would be the nest next step.
Re: WAS(8.5) + Spring Security: Using an LDAP Authentication Provider2013-03-14T06:07:33Z in response to SystemAdminHi, yeah I think that would be a good thing to do next. I will find out whether someone in my organisation can raise the PMR ticket about this. Thank you!

Hello. I found the solution. Installing IBM iFix 126.96.36.199-WS-WASProd-IFPM74498 fixed the problem in WAS 188.8.131.52. Not sure whether the same fix can be installed in 184.108.40.206 though.

Thank you so much for posting this response. This helped fix my problem.
Just an additional link for someone looking:
This fix went into 220.127.116.11 looks like.
