If the enterprise has an LDAP server, the platform can be configured to automatically authenticate users against the LDAP Server when they log in.

How LDAP Works

Platform Behavior, User Experience and Administration

When a user logs in, the platform carries out the following sequence of activities:

  • If their User record was created in the platform, they log in with those settings.
  • If the user is not known to the platform, the LDAP directory is searched for a matching entry.
  • If none is found, access is denied.
  • If a matching entry exists, a new LDAP-enabled User record is created.
  • Thereafter, when the user logs in, their password is validated against the LDAP directory.
  • At the same time, any changes made to the user's LDAP settings are synchronized with the platform.

As far as the user is concerned, therefore, they simply log in to the platform using the same credentials they use everywhere else.

And as far as admins are concerned, user information is maintained in one place--the LDAP server. Any changes made there are automatically seen by the platform.

Effect on User Profiles

When a user has an entry in an LDAP directory, most of their profile information is maintained in the LDAP server. The platform reads that information from the server. It can no longer be modified in the platform. The exception is profile information that is specific to the platform.

In particular:

  • In the initial dialog a user sees when they log in, the Reset Password option is disabled.
  • In the user's My Information page, only the user's Team affiliation and default Application can be modified. Other settings can be viewed, but not changed.
  • In the admin's Users page:
  • The option to Reset Password is disabled for LDAP users.
  • The user's Team affiliation and default Application can be modified. Other settings can be viewed, but not changed.

LDAP Address Expressions

In its simplest form, LDAP can be thought of as a hierarchy of directories, each of which contains entries for users and other entities. But instead of using a URL to address those directories, you use a combination of syntax elements.

For example, consider the URL http://yourCompany.com/united_states/california/users/yourLDAPdata.
That path is specified in LDAP elements using the elements below:

  • DC (Domain Controller) Used to specify the LDAP domain.
For example: DC=yourCompany, DC=com, which corresponds to yourCompany.com in the URL.
  • OU (Organizational Unit) A group that can contain other groups. (Effectively, an "intermediate" group.)
For example: OU=california, OU=united_states, which corresponds to the URL path /united_states/california.
  • CN (Common Name) A group that can contain individual entries, but which cannot contain subgroups.
For example: CN=users, which corresponds to the final directory in the URL.
Within that directory, the entry yourLDAPdata can be found.

Considerations and Limitations

  • Active Directory is currently supported. Open LDAP is under development.
  • A single LDAP server is supported, for now.
  • The search for a matching user does not yet span multiple groups, so a CN entry must be included either in the specification of the search directory, in the user or group directory designation, or in one of their filters. The search path cannot terminate at an Organizational Unit (OU) directory, as that would require searching the multiple subdirectories it contains.
  • The user's Team cannot currently be configured using LDAP attributes. The default team is always used for a new user.
    (The team setting can be changed in the platform after the user logs in.)
  • Similarly, to give a user access to multiple applications, or to change the user's initial application modify the Application Access settings after the user has logged in to the platform.

Working with LDAP

Configuring LDAP

  1. Examine the configuration settings below to see which individual-user attributes can be populated from LDAP.
  2. If desired, create attributes for those settings in your LDAP server.
    (If all users will have the same settings, this step is not necessary. They'll use the default settings you configure below.)
  3. Go to Settings > Administration > LDAP Configuration
  4. Fill in the configuration settings
  5. Click [Save]

Configuration Settings

  • Server Type - The type of LDAP server. Active Directory is the default.
  • Server URL - The server domain and optional portal. Secure portal #636 is the default.
For example: our.LDAPserver:998

  • Login DN - The Distinguished Name of a user that has admin privileges.
  • Password - The admin user's password.

  • Starting Search Directory
A comma-separated list of DC and OU expressions that leads to the start of the search path.
Optionally, include a CN directive as well, to completely specify the directory to be searched.

  • User DN - Optional. An LDAP expression that designates a path to an LDAP user directory, starting from the initial directory.
  • User DN Filter - Optional. An expression that limits the LDAP entries that will be examined.
For example, use a setting like this one to exclude disabled users: !(userAccountControl=514)
Note: The (objectCategory=person) and (objectClass=user) parameters do not need to be specified. They are included automatically.

  • Group DN - Optional. An LDAP expression that designates a path to an LDAP "group" (distribution list) directory, starting from the initial directory.
  • Group DN Filter - Optional. An expression that limits the LDAP entries that will be examined.
For example, use a setting like this to exclude entries that include the word "test": !(mail=*test*)
Note: The (objectCategory=group) parameter does not need to be specified. It is included automatically.

  • Default Team - A new user's default Team.
The team assignment can be changed in the platform after the user logs in.
The user can change it in My Information. An admin can do so in the Users page.

The user's access profile is fully determined by the LDAP configuration.
  • LDAP Attribute for Access Profile - The name of an LDAP field that designates the user's access profile.
The LDAP attribute must contain an access profile's record ID.
To get a record ID:
a. Go to Settings > Administration > Access Profiles
b. Modify the view to display Record IDs, and copy the ones you need.

  • Default Application - The initial Application the user sees when they log in.
That setting can be changed in the platform after the user logs in.
The user can change it in My Information. An admin can do so in the Users page.
To grant access to additional applications:
a. When the user logs in, a User record is created for them in the platform.
b. You can then use the Application Access page to specify the applications the user can access.
  • LDAP Attribute for Application - The name of an LDAP field that designates the user's application.
The LDAP attribute must contain the application's record ID.
To get a record ID:
a. Go to Settings > Administration > Application Access
b. Modify the view to display Record IDs, and copy the ones you need.

  • Default Role - The new user's Role in the application.
That setting can be changed in the platform after the user logs in.
The user can change it in My Information. An admin can do so in the Users page.
  • LDAP Attribute for Role - The name of an LDAP field that designates the user's role in the application.
The LDAP attribute must contain the role's record ID.
To get a record ID:
a. Open the application, if it is not already running.
b. Go to Designer > Roles
c. Modify the view to display Record IDs, and copy the ones you need.
