i have installed weblogic '10.3.4.0' and have created a user in the default security realm 'myrealm'. The authenticator is DefaultAuthenticator. Now, I have to authenticate the user through a stand alone java application. But the application is resposning with 'LDAP: error code 49 - Invalid Credentials': CODE-START ** Properties l_props = new Properties(); LdapContext l_ctx = null; l_props.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory"); l_props.put(Context.PROVIDER_URL, "ldap://localhost:7001"); l_props.put(Context.SECURITY_AUTHENTICATION, "simple"); l_props.put(Context.SECURITY_PRINCIPAL, "cn=username"); l_props.put(Context.SECURITY_CREDENTIALS, "password"); l_ctx = new InitialLdapContext(l_props, null); ** CODE-END ** * ERROR-START * javax.naming.AuthenticationException: [LDAP: error code 49 - Invalid Credentials] at com.sun.jndi.ldap.LdapCtx.mapErrorCode(LdapCtx.java:3041) at com.sun.jndi.ldap.LdapCtx.processReturnCode(LdapCtx.java:2987) at com.sun.jndi.ldap.LdapCtx.processReturnCode(LdapCtx.java:2789) at com.sun.jndi.ldap.LdapCtx.connect(LdapCtx.java:2703) at com.sun.jndi.ldap.LdapCtx.(LdapCtx.java:293) at com.sun.jndi.ldap.LdapCtxFactory.getUsingURL(LdapCtxFactory.java:175) at com.sun.jndi.ldap.LdapCtxFactory.getUsingURLs(LdapCtxFactory.java:193) at com.sun.jndi.ldap.LdapCtxFactory.getLdapCtxInstance(LdapCtxFactory.java:136) at com.sun.jndi.ldap.LdapCtxFactory.getInitialContext(LdapCtxFactory.java:66) at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:667) at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:288) at javax.naming.InitialContext.init(InitialContext.java:223) at javax.naming.ldap.InitialLdapContext.(InitialLdapContext.java:134) at com.iflex.fcat.misc.TestLDAP.createInitialLdapContext(TestLDAP.java:258) at com.iflex.fcat.misc.TestLDAP.authenticate(TestLDAP.java:170) at com.iflex.fcat.misc.TestLDAP.main(TestLDAP.java:125) ERROR-END
