Hi all, I have been trying to use a custom JAASRealm loginmodule in my code and running into exception or 403 access denied error message. I have searched for an answer in the Tomcat FAQ, on the net using general google search, searched the bugs list. But did not get an exact answer to the problem I am facing. Here is the details of the configuration and code I have setup on a tomcat 6.0.18 running on a Windows machine.
Tomcat 6.0.18 is running on a windows box. The following realm configuration is inside the 'Engine' element of the server.xml: <Realm className="org.apache.catalina.realm.JAASRealm" appName="securitytest" userClassNames="com.genuvation.commons.security.User" roleClassNames="com.genuvation.commons.security.Role" debug="99" /> Here is my jaas.config which is in the %CATALINA_HOME%/conf directory: securitytest { com.genuvation.commons.security.MyLoginModule required debug=true; }; This jaas.config file is specified in the %CATALINA_HOME%/bin/catalina.bat file as part of JAVA_OPT: set JAVA_OPTS=%JAVA_OPTS% -Djava.security.auth.login.config=%CATALINA_HOME%\conf\jaas.config Here is the source code for a custom loginmodule. This code is part of a common.jar class which has been compiled and placed as in the %CATALINA_HOME%/lib public class MyLoginModule implements LoginModule { private Subject subject; private CallbackHandler callbackHandler; private String password; private String name; public boolean abort() throws LoginException { return true; } public boolean commit() throws LoginException { subject.getPrincipals().add(new User(name)); subject.getPrincipals().add(new Role("role1")); System.out.println("The commit method succeeded in the loginmodule returning true"); } return true; } private boolean isBlank(String value){ boolean bRet = true; if(null!=value){ bRet = (value.trim()).isEmpty(); } return bRet; } public void initialize(Subject subject, CallbackHandler callbackHandler, Map<String, ?> sharedState, Map<String, ?> options) { this.subject = subject; this.callbackHandler = callbackHandler; } public boolean login() throws LoginException { NameCallback name = new NameCallback("User name"); PasswordCallback password = new PasswordCallback("Password", false); try { this.callbackHandler.handle(new Callback[] { name, password }); this.name = name.getName(); System.out.println("The name is" + this.name); if(password.getPassword()!=null) this.password = new String(password.getPassword()); if (isBlank(this.name)) { throw new CredentialNotFoundException("User name is required"); } if (isBlank(this.password)) { throw new CredentialNotFoundException("Password is required"); } return true ; } catch (Exception e) { throw new LoginException(e.getMessage()); } System.out.println("The login method succeeded in the loginmodule returning true"); return true; } public boolean logout() throws LoginException { return true; } } The following is the web.xm file security section: <security-constraint> <display-name>Example Security Constraint</display-name> <web-resource-collection> <url-pattern>/*</url-pattern> </web-resource-collection> <auth-constraint> <role-name>role1</role-name> </auth-constraint> </security-constraint> <login-config> <auth-method>BASIC</auth-method> <realm-name>authenticator-realm</realm-name> </login-config> <security-role> <role-name>role1</role-name> </security-role> When I run the tomcat instance with my web-app tbiservices.war file in the %CATALINA_HOME%/webapp directory and all the configuration in place and I hit the URL for the servlet, I get a browser dialog box popped up for Username and password as expected. When I put in any user-id, password in the box and hit ok, the page redirects to a "403 Access Denied" page without any message in the log. I can see that the loginmodule was hit, as the few system.out.println messages show up in the log. I tried, moving the JAASRealm to the web-app meta-inf/context.xml and setting contextclassloader = true in the realm did not work. moving the loginmodule containing common jar down to the webapp web-inf generates and exception that the loginmodule was not found. My question is, how can I make it work? Or is there a bug? It should just pop-up the dialog box and for any pair of user-password succeed and direct us to the resource. Please advise, or point to any appropriate bug/document etc. I can not make any progress without some more pointers. Thanks. -Andy Basu
