Revision as of 12:31, 24 July 2008 by Ebasso (talk | contribs)

Vamos configurar a consulta a um diretório LDAP ao repositório federado, para armazenar informações sobre as contas de usuários.

Obs. 1: Verifique que os servidores server1 e WebSphere_Portal estejam executando antes de iniciar está tarefa.

Obs. 2: Veja exemplos em /opt/IBM/WebSphere/wp_profile/ConfigEngine/config/helpers

Passos:

1. Backup dos arquivos de configuração

Vá para o diretório 

/opt/IBM/WebSphere/wp_profile/ConfigEngine/properties

faça um backup dos arquivos wkplc.properties 

cp wkplc.properties wkplc.properties_antesLDAP
cp wkplc_comp.properties wkplc_comp.properties_antesLDAP

2. Definições no arquivo wkplc.properties

Edite o arquivo wkplc.properties e defina o seguinte:

Na seção "VMM Federated LDAP Properties"

# The syntax is like a standard LDAP searchfilter like (objectclass=dominoGroup)
# In general this value can be left blank
federated.ldap.et.group.searchFilter=

# One or more object classes for the entity type.
federated.ldap.et.group.objectClasses=dominoGroup

# The object class to use when an entity type is created. If the value of this parameter is the same as the objectClass parameter, you do not need to specify this parameter.
federated.ldap.et.group.objectClassesForCreate=

# The search base or bases to use while searching the entity type.
federated.ldap.et.group.searchBases=

Na seção "LDAP entity types" - item "Entity type PersonAccount"

Na seção "Group member attributes"

# The name of the LDAP attribute that is used as the group member attribute. For example, member or uniqueMember.
federated.ldap.gm.groupMemberName=member

# The group object class that contains the member attribute. For example, groupOfNames or groupOfUnqiueNames.
# If you do not define this parameter, the member attribute applies to all group object classes.
federated.ldap.gm.objectClass=dominoGroup

# The scope of the member attribute. The valid values for this parameter include the following:
# direct - The member attribute only contains direct members.
# nested - The member attribute that contains the direct members and the nested members.
federated.ldap.gm.scope=direct

# If you create a group without specifying a member, a dummy member will be filled in to avoid creating an exception about missing a mandatory attribute.
federated.ldap.gm.dummyMember=uid=dummy

         * groupRdnProperties
  3. Save your changes to the wkplc.properties file.
  4. Run the ./ConfigEngine.sh wp-update-entitytypes -DWasPassword=password task, from the wp_profile_root/ConfigEngine directory, to update the Group and PersonAccount entity types with the corresponding default parent and relative distinguished name (RDN).
  5. Stop and restart the deployment manager, the node agent(s), server1, and the WebSphere_Portal servers.

(Opcional) 11. Habilitando Login através do Full Distinguished Name

Perform the following steps to enable the full distinguished name login if the short names are not unique for the realm: 

1. Use a text editor to open the wkplc.properties file, located in the wp_profile_root/ConfigEngine/properties directory.
2. Enter a value for realmName or leave blank to update the default realm.

(Opcional) 12. Executando o Member Fixer Tool

Obs.: Este passo é somente necessário se você estiver utilizando o WCM e quiser utilizar os Templates de Intranet e Internet.

Execute o Member Fixer tool para atualizar o nome dos membros usados pelo WCM, passos:

Vá para o diretório 

cd /opt/IBM/WebSphere/wp_profile/PortalServer/wcm/shared/app/config/wcmservices

Edite o arquivo MemberFixerModule.properties e defina o seguinte: 

  1. Edite o arquivo wp_profile_root/PortalServer/wcm/shared/app/config/wcmservices/MemberFixerModule.properties file.
  2. Update the contentAuthors_new property with the group name you used for the content authors group during LDAP configuration.
  3. Update the administrator_new property with the administrator user name you used for the administrator user during LDAP configuration. Note that the old administrator user value should be uid=xyzadmin,o=defaultWIMFileBasedRealm, which is the default administrator user used when the Intranet and Internet Site Templates are created.

Salve e feche o arquivo

Vá para o diretório 

/opt/IBM/WebSphere/wp_profile/ConfigEngine

e execute o seguinte comando 

#./ConfigEngine.sh action-express-memberfixer -DmemberfixerRealm=<realm_name> -DPortalAdminPwd=<password>

Note: that realm_name indicates the realm where these users and groups are stored (for example, -DmemberfixerRealm=defaultWIMFileBasedRealm).

13. Removendo o Repositório Federado em Arquivo

Após a integração com o LDAP a segurança default pode ser removida, evitando conflitos por usuários com identidades duplicadas.

1. Vá no console administrativo do Servidor 

https://wps1.empresax.com.br:10041/ibm/console

2. No Console Administrativo do WebSphere Application Server, selecione 

Em Inglês: Security > Secure administration, applications, and infrastructure > User Registry > Custom > Custom Properties

Em Português: Segurança > Segurança Global > Registro do Usuário > Customizar > Propriedades Customizadas

From the Deployment Manager or WebSphere Application Server administrative console, 
select Security > Secure administration, applications, and infrastructure.
2. In the User account repository section, make sure that Federated repositories is set in the Available realm definitions.
3. Clique em Configure.
4. In the list of Repositories in the realm, select the repository with the identifier InternalFileRepository.
5. Click Remove.



4. Salve suas alterações.

5. Sincronize todos os nós se você estiver em cluster



(Opcional) 14. Substituindo o Administrador do Portal LOCAL pelo do LDAP

Perform the following steps to replace the WebSphere Application Server and WebSphere Portal administrator user ID with users that exists in the LDAP user registry: 

  1. Run the ./ConfigEngine.sh wp-change-was-admin-user -DnewAdminId=newadminid –DnewAdminPw=newpassword task, from the wp_profile_root/ConfigEngine directory, to replace the old WebSphere Application Server administrative user with the new user.
     Note: This task verifies the user against a running server instance. If the server is stopped, add the -Dskip.ldap.validation=true parameter to the task to skip the validation.
  2. Verify that the task completed successfully. In a clustered environment, restart the deployment manager, the node agent(s), server1, and WebSphere_Portal servers. In a stand-alone environment, restart the server1 and WebSphere_Portal servers.
  3. Run the ./ConfigEngine.sh wp-change-portal-admin-user -DnewAdminId=newadminid –DnewAdminPw=newpassword -DnewAdminGroupId=newadmingroup task to replace the old WebSphere Portal administrative user with the new user.
     Note: This task verifies the user against a running LDAP server instance when LDAP security is enabled. If the LDAP server is stopped, add the -Dskip.ldap.validation=true parameter to the task to skip the validation.
  4. Verify that the task completed successfully. In a clustered environment, restart the deployment manager, the node agent(s), server1, and WebSphere_Portal servers. In a stand-alone environment, restart the server1 and WebSphere_Portal servers.
