User management functionality is provided by default in all WSO2 Carbon-based products and is configured in the user-mgt.xml file found in the <PRODUCT_HOME>/repository/conf/ directory. This file is shipped with user store manager configurations for all possible user store types (JDBC, read-only LDAP/Active Directory, read-write LDAP and read-write Active directory). The instructions given below explains how to configure a read-write LDAP as the primary user store for the WSO2 server.

...

1. Enable the <ReadWriteLDAPUserStoreManager> user store manager class in the user-mgt.xml file by uncommenting the relevant code. When it is enabled, the user manager reads/writes into the LDAP user store. 

   Note
   Note that these configurations already exist in the user-mgt.xml file so you only need to uncomment them and make the appropriate adjustments.Also ensure that you comment out the configurations for other user stores that you are not using; in short, you can only configure one primary user store.

2. The default configuration for the external read/write user store in the user-mgt.xml file is as follows. You may have to change some of these values according to your requirements. For more information about each of the properties used in the user-mgt.xml file for configuring the primary user store, see Properties of User Stores. 

   Code Block
   language html/xml
   <UserStoreManager class="org.wso2.carbon.user.core.ldap.ReadWriteLDAPUserStoreManager"> <Property name="TenantManager">org.wso2.carbon.user.core.tenant.CommonHybridLDAPTenantManager</Property> <Property name="ConnectionURL">ldap://localhost:${Ports.EmbeddedLDAP.LDAPServerPort}</Property> <Property name="ConnectionName">uid=admin,ou=system</Property> <Property name="ConnectionPassword">admin</Property> <Property name="PasswordHashMethod">SHA</Property> <Property name="UserNameListFilter">(objectClass=person)</Property> <Property name="UserEntryObjectClass">wso2Person</Property> <Property name="UserSearchBase">ou=Users,dc=wso2,dc=org</Property> <Property name="UserNameSearchFilter">(&amp;(objectClass=person)(uid=?))</Property> <Property name="UserNameAttribute">uid</Property> <Property name="PasswordJavaScriptRegEx">[\\S]{5,30}</Property> <Property name="UsernameJavaScriptRegEx">[\\S]{3,30}</Property> <Property name="UsernameJavaRegEx">[a-zA-Z0-9._\-|/]{3,30}$</Property> <Property name="RolenameJavaScriptRegEx">[\\S]{3,30}</Property> <Property name="RolenameJavaRegEx">[a-zA-Z0-9._\-|/]{3,30}$</Property> <Property name="ReadGroups">true</Property> <Property name="WriteGroups">true</Property> <Property name="EmptyRolesAllowed">true</Property> <Property name="GroupSearchBase">ou=Groups,dc=wso2,dc=org</Property> <Property name="GroupNameListFilter">(objectClass=groupOfNames)</Property> <Property name="GroupEntryObjectClass">groupOfNames</Property> <Property name="GroupNameSearchFilter">(&amp;(objectClass=groupOfNames)(cn=?))</Property> <Property name="GroupNameAttribute">cn</Property> <Property name="SharedGroupNameAttribute">cn</Property> <Property name="SharedGroupSearchBase">ou=SharedGroups,dc=wso2,dc=org</Property>  <Property name="SharedGroupEntryObjectClass">groups</Property> <Property name="SharedTenantNameListFilter">(object=organizationalUnit)</Property> <Property name="SharedTenantNameAttribute">ou</Property> <Property name="SharedTenantObjectClass">organizationalUnit</Property> <Property name="MembershipAttribute">member</Property> <Property name="LDAPConnectionTimeout">5000</Property> <Property name="UserRolesCacheEnabled">true</Property> <Property name="UserDNPattern">uid={0},ou=Users,dc=wso2,dc=org</Property> </UserStoreManager>

   1. To read and write to an LDAPuserstore, it is important to ensure that the ReadGroups and WriteGroups properties in the <PRODUCT_HOME>/repository/conf/user-mgt.xml file are set to true.

      Code Block
      language xml
      <Property name="ReadGroups">true</Property> <Property name="WriteGroups">true</Property>

   2. Set the attribute to use as the username, typically either cn or uid for LDAP. Ideally, <Property name="UserNameAttribute"> and <Property name="UserNameSearchFilter"> should refer to the same attribute. If you are not sure what attribute is available in your user store, check with your LDAP administrator. 

      Code Block
      language html/xml
      <Property name="UserNameAttribute">uid</Property>

   3. Specify the following properties that are relevant to connecting to the LDAP in order to perform various tasks.

      Code Block
      language xml
      <Property name="ConnectionURL">ldap://localhost:${Ports.EmbeddedLDAP.LDAPServerPort}</Property> <Property name="ConnectionName">uid=admin,ou=system</Property> <Property name="ConnectionPassword">admin</Property>

      Note
      If you are using ldaps (secured LDAP) to connect to the LDAP: You need set the ConnectionURL as shown below. Code Block language xml <Property name="ConnectionURL">ldaps://10.100.1.100:636</Property> You also need to enable connection pooling for LDAPS connections at the time of starting your server, which will enhance server performance.

   4. In WSO2 products based on Carbon 4.4.x, you can set the LDAPConnectionTimeout property: If the connection to the LDAP is inactive for the length of time (in milliseconds) specified by this property, the connection will be terminated.

   5. Set the ReadGroups property to 'true', if it should be allowed to read roles from this user store. When this property is 'true', you must also specify values for the GroupSearchBase, GroupSearchFilter and GroupNameAttribute properties. If the ReadGroups property is set to 'false', only Users can be read from the user store. You can set the configuration to read roles from the user store by reading the user/role mapping based on a membership (user list) or backlink attribute as shown below.
      
      To read the user/role mapping based on a membership (This is used by the ApacheDirectory server and OpenLDAP): 

      • Enable the ReadGroups property.

        Code Block
        language html/xml
        <Property name="ReadGroups">true</Property>

      • Set the GroupSearchBase property to the directory name where the Roles are stored. That is, the roles you create using the management console of your product will be stored in this directory location. Also, when LDAP searches for groups, it will start from this location of the directory. For example:

        Code Block
        language html/xml
        <Property name="GroupSearchBase">ou=system,CN=Users,DC=wso2,DC=test</Property>

      • Set the GroupSearchFilter andGroupNameAttributes. For example:

        Code Block
        language html/xml
        <Property name="GroupSearchFilter">(objectClass=groupOfNames)</Property> <Property name="GroupNameAttribute">cn</Property>

      • Set the MembershipAttribute property as shown below:

        Code Block
        language html/xml
        <Property name="MembershipAttribute">member</Property>

      To read roles based on a backlink attribute, use thefollowingcodesnipetinsteadofthe above:

      Code Block
      language html/xml
      <Property name="ReadGroups">false</Property> <Property name="GroupSearchBase">ou=system</Property> <Property name="GroupSearchFilter">(objectClass=groupOfNames)</Property> <Property name="GroupNameAttribute">cn</Property> <Property name="MembershipAttribute">member</Property> <Property name="BackLinksEnabled">true</Property> <Property name="MembershipOfAttribute">memberOf</Property>
