A security realm defines the mechanism for user authentication and authorization. FlexDeploy provides a default internal realm for users, which is based on FlexDeploy database tables for users and groups. FlexDeploy also supports LDAP and SSO based realms for authentication and authorization using an external directory server. You can define multiple LDAP security realms, or one SSO realm. To configure and view the realms, navigate to Realms from the menu or global search. FlexDeploy’s out-of-the-box realm can be utilized alongside external directory servers.
...
If group mapping is enabled for a an external realm, an external user’s groups are derived from mapping configured for that realm. Groups assigned in the FlexDeploy internal realm are always used as well, so you can provide additional groups to users defined in an external realm from the groups screen or from individual user profiles. If you choose not to enable group mapping, you must assign groups to users manually in FlexDeploy.
External realm users will have their passwords managed in the external realm, not in FlexDeploy.
...
New User Process
| Info |
|---|
A user account must exist in FlexDeploy even for external realm users. This is necessary so that users can control notification settings and administrators can provide additional security, if necessary. Administrators can create external realm users from the Users page, or external realm users can login and create their own account. When users defined in an external realm login successfully for the first time, they will be redirected to a new user page. There, the user is asked to verify various information like first name, last name, and email for their account. The password for such users is always managed by the external server. Once the user provides the necessary details, their account will be created, an automatic logout will occur, and the user will have to login one more time. At this point, the user will be granted access based on realm group mapping configured by an administrator, which is explained later in this document. If the new user isn’t mapped to any FlexDeploy groups at this point, they will be assigned the new user role configured on the System Settings page, if one exists. |
Create / Edit Realm
To create a new realm, click the Create button. To edit an existing realm, click the realm name or select Edit from the options menu. Note that the internal fdRealm cannot be edited. Use the Active button to activate or inactivate a specific realm. You can use the Delete option in each row’s menu to completely remove a specific realm from FlexDeploy configurations.
Any changes to a realm's configuration will require the FlexDeploy application server to be restarted for the changes to take effect. This does not include updating group mappings. You can test realm configuration details by clicking the Test Connection button.
Enter the details for the LDAP realm as described in table of inputs below. Click the Save button to save your changes.

| Info |

FlexDeploy uses the memberOf virtual attribute to derive a user's groups, so group mapping will not work if your LDAP does not support that attribute. |
...
Field

Required
...
Description
...
...
Yes
...
Description
...
No
...
URL
...
Yes
...
URL to access LDAP server
For example, ldap://localhost:10389
...
System Username
...
Yes
...
Read-only username to access LDAP server. This should be fully qualified username in LDAP. FlexDeploy will use the system username and system password to bind to LDAP for various operations.
For example, uid=admin,ou=system
...
System Password
...
Yes
...
Password for specified system user name.
...
User Search Base
...
Yes
...
User base tree in LDAP server
For example, ou=users,ou=system.
...
User Search Filter
...
Yes
...
User search filter to find user records in user search base
For example, (&(objectClass=*)(uid={0})), (&(objectClass=*)(sAMAccountName={0}))
| Tip |
|---|
To restrict users able to login to FlexDeploy by membership within a particular LDAP group, you can use a search filter similar to the following. This assumes that your LDAP supports the memberOf virtual attribute. (objectClass=user)(sAMAccountName={0})(memberOf=CN=FDDevelopers,CN=Users,DC=flexagondev,DC=local) Similarly, more than one group would look like this. (&(objectClass=user)(sAMAccountName={0})(|(memberOf=CN=FDDevelopers,CN=Users,DC=flexagondev,DC=local)(memberOf=CN=FDAdmins,CN=Users,DC=flexagondev,DC=local)) |

Yes
...
@since 6.5.0.2
How to handle referrals (follow/ignore). The default is ignore.

Group base tree in LDAP server. Required if group mapping is enabled.
For example, (ou=groups,ou=myrealm,dc=MyDomain)
...
Group Search Filter
...
No*
...
Search filter to find groups in group search base. Required if group mapping is enabled.
For example, (objectClass=groupOfUniqueNames)
...
FlexDeploy provides features to map external directory server groups to FlexDeploy groups, which makes it very easy to manage FlexDeploy users in your environment. Fine-grained access to FlexDeploy features is still controlled by FlexDeploy groups, and by mapping external directory groups to FlexDeploy groups, you essentially control access to FlexDeploy features. You can configure FlexDeploy group permissions using the Permissions page and from the Security section of individual objects supporting object-level permissions (folders/projects, target groups, releases, etc.).
In order to set up group mapping, first make sure to enable group mapping from the realm’s group mapping tab and provide the group search base and filter. If you haven’t already loaded external groups for this realm or they need to be refreshed, click the Fetch External Groups button or the Refresh External Groups button.
...
Realm configuration changes including the mapping configuration require a recycle of the FlexDeploy server process, but changes to the groups being mapped do not require a recycle.
...
Examples
Apache Directory Server Realm
...
Active Directory Realm
...
FlexDeploy will use the User logon name (pre-Windows 2000) username instead of the normal one for active directory. See this picture for an example.
...
Using ldaps
A FlexDeploy realm can be configured to use ldaps protocol, which requires adding a server certificate to Java cacerts or the application server trust store.
You may encounter java.security.cert.CertificateException: No subject alternative names present when using SSL connection and the hostname in connection URL is not valid when compared to the SSL certificate of the server. This error occurs in java 1.8.0_181 or higher is because this update includes security improvements for LDAP support. Endpoint identification has been enabled on LDAPS connections. In this situation, you must regenerate the LDAP server certificate with the certificate’s SAN or CN matching the hostname of the LDAP server configured in connection URL. This is not recommended for production installation, but you can temporarily disable this by adding -Dcom.sun.jndi.ldap.object.disableEndpointIdentification=true to server startup arguments.
