Omar I actually had this exact same problem early today although I'm sure my environment is slightly different from your perhaps I can offer some help.
In my case I have LDAP authentication configured for my servlet. I believe this step should be the same regardless of the authentication scheme you are using.... First I edit CATALINA_HOME/webapps/myServelet/WEB-INF/web.xml to define roles and constraints for what pages can be accessed... <login-config> <auth-method>BASIC</auth-method> </login-config> <security-role> <role-name>GRP-myGroup </role-name> </security-role> <security-constraint> <web-resource-collection> <web-resource-name>my Authentication</web-resource-name> <url-pattern>/*</url-pattern> </web-resource-collection> <auth-constraint> <role-name>GRP-myGroup</role-name> </auth-constraint> </security-constraint> The other file I change sets up all the LDAP machine details. I've placed it in Context.xml because there are several servlets that make use of this authentication... $CATALINA_HOME/conf/Context.xml <Context> <Realm className ="org.apache.catalina.realm.JNDIRealm" debug ="99" connectionURL ="ldap://ldapMachine:3268" connectionName ="CRYPTOLOGIC\myUser" connectionPassword="myPassword" userBase ="dc=myDomain,dc=com" userSearch ="(sAMAccountName={0})" userSubtree ="true" userRoleName ="memberOf" roleBase ="OU=Groups,DC=myDomain,DC=com" roleSubtree="false" roleName ="cn" roleSearch ="(member={0})"/> </Context> This has worked for me. Hope it is of some use to you. We also have Apache over top of Tomcat in our environment and found it necessary to configure authentication both in Apache and in Tomcat to get things to work properly.
