Programmatically Authenticate LDAP user in AEM

user_5729306 0
Viewed 1145

I've set up local LDAP server Created user and group. Configured LDAP in AEM config manager and synchronized the users and group.

Using, ExternalIdentityProvider as a service reference, I'm able to get list of LDAP users I.e. I am able to validate if the user is present in LDAP or not.

But, I'm not able to validate user credentials using authentic method of the above mentioned API.

Am I missing any configuration specifics or the approach that I'm using is wrong ?

Updated:

Authentication code:

@Reference
private ExternalIdentityProviderManager externalIdentityProviderManager;

final String externalId = request.getParameter("externalId");
final String externalPassword = request.getParameter("externalPassword");

final ExternalIdentityProvider idap = externalIdentityProviderManager.getProvider("ldap");
final SimpleCredentials credentials = new SimpleCredentials(externalId, externalPassword.toCharArray());
final ExternalUser externalUser = idap.authenticate(credentials);

Error thrown - 

javax.security.auth.login.LoginException: Unable to authenticate against LDAP server: INVALID_CREDENTIALS: Bind failed: Attempt to lookup non-existant entry: cn=steve+uid=steve+sn=jobs,dc=example,dc=com

For LDAP Login you need 3 OSGi configs. The most difficult one, you already have.

  • External Login Module (containing a reference to the next two)
  • LDAP Identity Provider (how to access the LDAP)
  • Sync Handler (mapping the LDAP data to AEM user data)

Here an example:

org.apache.jackrabbit.oak.spi.security.authentication.external.impl.ExternalLoginModuleFactory-emea

"jcr:primaryType": "sling:OsgiConfig",
"jaas.ranking": "50",
"jaas.controlFlag": "SUFFICIENT",
"jaas.realmName": "",
"idp.name": "ldap-emea",
"sync.handlerName": "sync-emea"

org.apache.jackrabbit.oak.security.authentication.ldap.impl.LdapIdentityProvider-emea

"jcr:primaryType": "sling:OsgiConfig",
"provider.name": "ldap-emea",
"host.name": "ldap-emea.emea.mycompany.internal",
"host.port": "3269",
"host.ssl": true,
"host.tls": true,
"host.noCertCheck": false,
"bind.dn": "CN=xxxx,OU=xxxx,OU=xxxx,OU=xxxx,DC=emea,DC=dir",
"bind.password": "very secret",
"searchTimeout": "60s",
"adminPool.maxActive": "8",
"adminPool.lookupOnValidate": true,
"userPool.maxActive": "8",
"userPool.lookupOnValidate": true,
"user.baseDN": "DC=emea,DC=dir",
"user.objectclass": "user",
"user.idAttribute": "sAMAccountName",
"user.extraFilter": "xxx very specific LDAP query xxxxx",
"user.makeDnPath": false,
"group.baseDN": "OU=Groups,OU=Common,DC=emea,DC=dir",
"group.objectclass": "group",
"group.nameAttribute": "cn",
"group.extraFilter": "xxx very specific LDAP query xxxxx",
"group.makeDnPath": false,
"group.memberAttribute": "member",
"customattributes": []

org.apache.jackrabbit.oak.spi.security.authentication.external.impl.DefaultSyncHandler-emea

"jcr:primaryType": "sling:OsgiConfig",
"handler.name": "sync-emea",
"user.expirationTime": "1h",
"user.autoMembership": [],
"user.propertyMapping": [
   "rep:fullname=cn",
   "profile/email=mail",
   "profile/familyName=sn",
   "profile/givenName=givenName",
   "profile/aboutMe=description",
   "profile/country=co",
   "profile/jobTitle=department",
   "profile/phoneNumber=telephoneNumber",
   "profile/mobile=mobile",
   "profile/postalCode=postalCode",
   "profile/street=streetAddress",
   "preferences/language=\"en\""
],
"user.pathPrefix": "my-company/emea",
"user.membershipExpTime": "1h",
"user.membershipNestingDepth": "3",
"group.expirationTime": "1d",
"group.autoMembership": [],
"group.propertyMapping": [
   "profile/givenName=name",
   "profile/aboutMe=description"
],
"group.pathPrefix": "my-company/nested/emea",
"user.dynamicMembership": false,
"user.disableMissing": false,
"enableRFC7613UsercaseMappedProfile": false

kind regards, Alex

I additionally setup an Apache Directory Server and filled it with the sample data (Sailors of the seven seas) http://directory.apache.org/apacheds/basic-ug/1.5-sample-configuration.html

The following configuration worked for me (synced users and groups via JMX, successful login of a user, including auto sync):

http://localhost:4502/apps/ldap-test.9.json

  {
  "jcr:primaryType": "nt:folder",
  "config": {
    "jcr:primaryType": "sling:Folder",
    "org.apache.jackrabbit.oak.security.authentication.ldap.impl.LdapIdentityProvider-test": {
      "jcr:primaryType": "sling:OsgiConfig",
      "provider.name": "ldap-test-alex",
      "host.name": "localhost",
      "host.port": "10389",
      "host.ssl": false,
      "host.tls": false,
      "bind.dn": "uid=admin,ou=system",
      "bind.password": "secret",
      "user.objectclass": "person",
      "user.baseDN": "ou=people,o=sevenSeas",
      "user.idAttribute": "uid",
      "group.objectclass": "groupOfUniqueNames",
      "group.baseDN": "ou=groups,o=sevenSeas",
      "group.nameAttribute": "cn",
      "group.memberAttribute": "uniquemember",
    },
    "org.apache.jackrabbit.oak.spi.security.authentication.external.impl.DefaultSyncHandler-test": {
      "jcr:primaryType": "sling:OsgiConfig",
      "handler.name": "ldap-sync-test-alex",
      "user.pathPrefix": "ldap-test",
      "group.pathPrefix": "ldap-test",
      "user.membershipNestingDepth": 1,
      "user.autoMembership": [
        "contributor"
      ],
      "user.propertyMapping": [
        "profile/email=mail",
        "profile/familyName=sn",
        "profile/givenName=givenName",
        "profile/aboutMe=description"
      ]
    },
    "org.apache.jackrabbit.oak.spi.security.authentication.external.impl.ExternalLoginModuleFactory-test": {
      "jcr:primaryType": "sling:OsgiConfig",
      "idp.name": "ldap-test-alex",
      "sync.handlerName": "ldap-sync-test-alex",
      "jaas.controlFlag": "SUFFICIENT",
      "jaas.ranking": "50"
    }
  }
}

Check, to have the following

  • know or set the password for the test user
  • set user.autoMembership to contributor (to see more than a white screen after a successful login)
  • check the OSGi config in the Felix console, maybe you missed the type or mispelled a config option
  • Check the log-file for hints
