Secure LDAP Configuration
will frevvo will be connecting to your LDAP server over the network. Here are two methods to secure the LDAP connection:
...
| Note |
|---|
Self signed certificates are not supported for frevvo Online. Although they are supported for in frevvo in-house, use of self-signed certificates is not recommended. |
Finally you need to install your signed or self-signed certificate. You can import the certificate into a keystore that can that frevvo can access and trust. Follow the instructions for your keystore. If is If frevvo is installed in a tomcat server, the tomcat keystore can be used. Refer to this Apache Tomcat website for instructions .

Configuring LDAPs for your Cloud tenant
Once your Online frevvo Online cloud hosted tenant has been provisioned for production use, follow the steps below to configure your tenant to use the frevvo LDAP/Active Directory Security Manager to integrate with your company's AD server:
- Confirm that your LDAP/AD server is running LDAPs with a third-party certification authority.
- It is likely your LDAP/AD server already has a CA certificate installed. But if not, this Microsoft KB article tells you how to do this: It is important that the hostname in the certificate matches the hostname in your ldaps url.
Your LDAP/AD server must be running LDAPs with a third-party certification authority BEFORE performing Step 4.
Warning Self signed certificates are not supported for frevvo Online tenants
- Customers that use firewall white-listing must add the frevvo cloud outgoing server IP 54.86.85.105 (host outgoing.frevvo.com) to the list.
Email your frevvo Security Manager resource. The frevvo infrastructure team will white label your server and port using the information provided.
Provide frevvo with the following:
the DNS Name(s) of the machine(s) hosting your AD server AND the IP Address or range of IP Addresses (in the case where your LDAP config is fault tolerant) of the machine(s) hosting your AD server.
- STOP:
- Wait for a reply email from your frevvo Security Manager resource letting you know that the frevvo infrastructure team has completed the white listing of your IP(s) on port 636 (ssl) or port 389 (TLS) in our firewall and verified connectivity.
- Once you receive this white listing confirmation email verify that you have completed:
- the Prerequisite Tasks listed below
- collected the information in the Key Information to Collect topic below
- Go to https://app.frevvo.com
- Login as your tenant admin
- Click on the Edit tenant link
Change the security manager to the LDAP Security Manager.
Warning If you have developed projects/forms/workflows in your starter/trial cloud tenant that you want to preserve, download them to your desktop as a backup BEFORE changing the existing Security Manager to the LDAP Security Manager.
- Change the LDAP properties to your company's AD server following the instructions listed below
- Save your tenant AD configuration settings
Verify that your tenant is now connected to your company AD server
...
Active Directory Customers using LDAP must ensure frevvo.TenantAdmin and frevvo.Designer groups are specified on your LDAP/AD server. The group names must be spelled as shown. Upper/lower case may be a factor for Open LDAP systems.
- Tenant admin users must be assigned to the frevvo.TenantAdmin group.
- Designer users must be assigned to the frevvo.Designer group. Note that, unlike the default security manager, users in the frevvo. Designer group
- TenantAdmin group must also be in the frevvo.Designer group to design forms/workflows.

frevvo and LDAP/Active Directory
users frevvo users and groups can be maintained externally in systems such as Active Directory or Open LDAP. Follow these steps to integrate and integrate frevvo and your LDAP server:
- Collect the key information listed below and verify the Prerequisite Tasks have been performed.
- Create a tenant with the LDAP Security Manager class.
...
- LDAP server name or ip
- LDAP server port
- User name and password with proper permissions to access and browse LDAP.
- LDAP groups and/or users that will be considered frevvo designers. These users will be able to create forms and workflows in frevvo.
- LDAP groups and users that will be considered administratorsfrevvo administrators.
- LDAP groups and users that will be considered publishersfrevvo publishers. This role gives a user the permission to go to the home page of every other tenant user.
- LDAP groups and users that will be considered ReadOnly.
- LDAP user and groups base filters
- LDAP all users and all groups filters
LDAP the attribute names in your Active Directory for UserId Display, GroupId Display, User Member Of, Group Member, First Name, Last Name, Email and Manager (optional)

Enter your LDAP Configuration Properties. Alternatively, you can start off from one of the sample configurations and provide only the key information listed above. See above for information on the TLS checkbox.
Note The Name/value table highlighted in the image allows you to configure up to 10 additional LDAP properties. See this Oracle website for a complete list of all available LDAP properties. For example, you can configure
to frevvo to ignore or follow referrals.
Setting the java.naming.referral property to a value of "ignore" in the Name/Value table configures
to frevvo to ignore referrals. Consult your LDAP Administrator for the details.
If you are creating a new tenant:- Enter a tenant id, a tenant name and description.
- The Max Concurrent Users is the maximum allowed by your license or less.
- Specify the LDAP User ID that will have the tenant admin permission. If editing an existing tenant, verify that the tenant admin user id is the LDAP user id for the tenant admin.
- Click Submit. You will see your new tenant in the tenant list if the connection to your LDAP server is successful.
| Warning |

The Ignore Case and Notify checkboxes are checked by default. It is recommended that you leave them checked. Refer to Mixed or Upper case User Names topic for an explanation of the Ignore Case option. The Notify checkbox determines whether the task notification emails (including new task, rejection, escalation and reminders) setup in workflows frevvo workflows are sent or not. |
Clicking the submit button tests the connection. Any errors are displayed at the top of the form. Here is an example of an error when there is a typo in the LDAP server name:
...
When you create a new tenant you are prompted to set up a tenant admin user id, password and email address. This tenant admin does not authenticate via your LDAP IDP. It only exists in frevvo. If you experience an issue with your LDAP configuration such that you can't login as an Active Directory authenticated user, use th built-in admin to login to your tenant as a tenant admin in order to fix your configuration issue. The built-in is able to access the tenant frevvo tenant admin functions if your LDAP Server should become inaccessible. Only one built-in tenant admin account is supported.
...
Browse this URL to login as the built-in: <base_URL>/frevvo/web/admin/login. When specified, will frevvo will prepend the base URL to the URLs in your Form/Document Actions. The <base_URL> is typically http(s)://<your servername>:<port>. For cloud customers the <base> is always https://app.frevvo.com.
You must use the admin specific URL - <base-url>/frevvo/web/admin/login - to login as the built-in.
Non admin users can also login using the admin specific URL.
...
Here are some quick tests to check if the LDAP configuration is correct:
- Login as the tenant frevvo tenant admin for the LDAP tenant.
- Click on the Manage Users link.
- Click All. You should see a list of LDAP users which were assigned one of these roles frevvo roles on the LDAP server: frevvo.TenantAdmin, frevvo.Designer, frevvo.Publisher, frevvo.ReadOnly
- Now, click Back To Manage Tenant.
- Click Manage Roles. You should see a list of groups from your LDAP server.
- Log out from from frevvo (you should be currently logged in as the tenantadmin)
- Try to login with the user name and password of a designer user in LDAP. You need to specify the proper tenant when logging in. For instance, if john is a valid LDAP user and the name of the LDAP tenant is MYLDAP, you should log in as john@MYLDAP. The password would be john's password in LDAP. Verify that the Project Home Page displays.
- Log out from frevvo
- Try to login with the user name and password of a non-designer user in LDAP. Verify that the user's Task List displays.
Since you are using LDAP to define users frevvo users and roles (i.e., groups), you do not see an Add User icon or Add Role icon on the Manage Users or Manage Roles pages.

Mixed or Uppercase User Names
| Info |
|---|
frevvo user names are case sensitive; the user name johndoe'' is not the same as JohnDoe. Several LDAP systems are case insensitive. Thus the two user names would resolve to the same LDAP account but to different frevvo user accounts. To avoid case issues follow these steps described in more detail below:
|
The first issue occurs when the user logs in. For instance, John Stevens LDAP account is JStevens but he logs in as jstevens, he will be recognized by case insensitive LDAP and thus granted access but will not be recognized as a designer or as a tenant admin by frevvo. To solve this, check the Ignore Case checkbox on the LDAP Configuration screen. To prevent issues you could always login to frevvo using lower case jstevens. LDAP will grant access as it is case insensitive and frevvo will know that you may have the designer or admin special permission. However users can forget to do this. Setting Ignore Case in your LDAP security configuration will solve this.
The second problem is in directing tasks to users frevvo users if your LDAP user names are mixed case. One solution is to use hidden controls on your forms with rules to convert the case of user names to lower case. The example below shows two text controls on a form, one visible, EmployeeMixedCase, and the other hidden, Employee.
...
LDAP administrators can configure to frevvo to ignore or follow referrals by entering the LDAP property name and value in the table provided on the Add Tenant (on-premise) or Edit Tenant (cloud) screens.
