Spring security 3.1 authentication LDAP with md5 -


when try authenticate using spring authentication manager, says "bad credentials":

authentication request = new usernamepasswordauthenticationtoken("john", "johnldap"); result = authenticationmanager.authenticate(request);

here securityapplicationcontext.xml file:

  <authentication-manager alias="authenticationmanager">         <ldap-authentication-provider server-ref="ldaplocal"             user-dn-pattern="uid={0},ou=people,dc=example,dc=com">                  </ldap-authentication-provider>      </authentication-manager>     <ldap-server url="ldap://127.0.0.1:389/dc=example,dc=com" manager-dn="admin" manager-password="xxxxxxxx" id="ldaplocal"  />

however using "ldapsearch" can connect successfully:

ldapsearch -d "uid=john,ou=people,dc=example,dc=com" -w johnldap  -l "objectclass=*"

at first time thought issue we've tell spring md5 of password before call ldap. add applicationsecurtycontext.xml:

    <beans:bean id="passwordencoder"  class="org.springframework.security.authentication.encoding.md5passwordencoder">     </beans:bean>     <authentication-manager alias="authenticationmanager">         <ldap-authentication-provider server-ref="ldaplocal"             user-dn-pattern="uid={0},ou=people,dc=example,dc=com">            <password-compare>             <password-encoder ref="passwordencoder"> </password-encoder>         </password-compare>         </ldap-authentication-provider>      </authentication-manager>     <ldap-server url="ldap://127.0.0.1:389/dc=example,dc=com" manager-dn="admin" manager-password="xxxxxxxx" id="ldaplocal"  />

but when add tag says:

ldap: error code 34 - invalid dn]

what's wrong here?

if remember correctly user-dn-pattern should not contain root dn, automatically appended. try using:

user-dn-pattern="uid={0},ou=people">

and don't think need password-encoder if want simple bind authentication.
