Hello, I have an application which uses LTPA to talk to a LDAP server . Theapplication ran sucessfully in WAS 3.5.x and when upgraded to 4.0x I intermittently get this error message . There were no changes made other than the packaging according to 4.0 standards .... Any help ??? JSAS0240E: Login failed. Verify the userid/password is correct. Check the properties file to ensure the login source is valid. If this error occurs on the server, check the server properties to ensure the principalName has a valid realm and userid.
