In our project we have implemented form based authentication. The user-role-password information is in Plain text files. I have used custom registry and the "com.ibm.websphere.security.FileRegistrySample" as the reader for these text files. Websphere5.1 seems to be authenticating the user but afterwards, the call to request.getUserPrincipal() returns null. Also the call to request.getAuthType() returns null whereas I have set it to "FORM". Please tell what may be going wrong. Eagerly waiting for a reply.
