You can configure Crowd to work with Microsoft Active Directory by setting up an LDAP connector in Crowd. If you wish to use Crowd to add users or change passwords in Active Directory, you will need to install an SSL certificate generated by your Active Directory server and then install the certificate into your JVM keystore.

On this page:

There's a Confluence SSL plugin that facilitates this process.

Updating user, group, and membership details in Active Directory requires that your Atlassian application be running in a JVM that trusts the AD server. To do this, we generate a certificate on the Active Directory server, then import it into Java's keystore.

Prerequisites

To generate a certificate, you need the following components installed on the Windows Domain Controller to which you're connecting.

Required Component

Description

Internet Information Services (IIS)

This is required before you can install Windows Certificate Services.

Windows Certificate Services

This installs a certification authority (CA) which is used to issue certificates. Step 1, below, explains this process.

Windows 2000 Service Pack 2

Required if you are using Windows 2000

Windows 2000 High Encryption Pack (128-bit)

Required if you are using Windows 2000. Provides the highest available encryption level (128-bit).

Step 1. Install the Active Directory Certificate Services

If Certificate Services are already installed, skip to step 2, below. The screenshots below are from Server 2008, but the process is similar for Server 2000 and 2003.

  1. Log in to your Active Directory server as an administrator.
  2. Click Start, point to Administrative Tools, and then click Server Manager.
  3. In the Roles Summary section, click Add Roles.

  4. On the Select Server Roles page, select the Active Directory Certificate Services check box. Click Next twice.

  5. On the Select Role Services page, select the Certification Authority check box, and then click Next.

  6. On the Specify Setup Type page, click Enterprise, and then click Next.

  7. On the Specify CA Type page, click Root CA, and then click Next.

  8. On the Set Up Private Key and Configure Cryptography for CA pages, you can configure optional configuration settings, including cryptographic service providers. However, the default values should be fine. Click Next twice.

  9. In the Common name for this CA box, type the common name of the CA, and then click Next.

  10. On the Set Validity Period page, accept the default values or specify other storage locations for the certificate database and the certificate database log, and then click Next.

  11. After verifying the information on the Confirm Installation Selections page, click Install.

  12. Review the information on the results screen to verify that the installation was successful.

Step 2. Obtain the Server Certificate

The steps above describe how to install the certification authority (CA) on your Microsoft Active Directory server. Next, you will need to add the Microsoft Active Directory server's SSL certificate to the list of accepted certificates used by the JDK that runs your application server.

The Active Directory certificate is automatically generated and placed in root of the C:\ drive, matching a file format similar to the tree structure of your Active Directory server. For example: c:\ad2008.ad01.atlassian.com_ad01.crt.

You can also export the certificate by executing this command on the Active Directory server:

Step 3. Import the Server Certificate

For an application server to trust your directory's certificate, the certificate must be imported into your Java runtime environment. The JDK stores trusted certificates in a file called a keystore. The default keystore file is called cacerts and it lives in the jre\lib\security sub-directory of your Java installation.

In the following examples, we use server-certificate.crt to represent the certificate file exported by your directory server. You will need to alter the instructions below to match the name actually generated.

Once the certificate has been imported as per the below instructions, you will need to restart the application to pick up the changes.

Windows

  1. Navigate to the directory in which Java is installed. It's probably called something like C:\Program Files\Java\jdk1.5.0_12.
  2. Run the command below, where server-certificate.crtis the name of the file from your directory server:

  3. keytool will prompt you for a password. The default keystore password is changeit.
  4. When prompted Trust this certificate? [no]: enter yesto confirm the key import:

    Enter keystore password:  changeit
    Owner: CN=ad01, C=US
    Issuer: CN=ad01, C=US
    Serial number: 15563d6677a4e9e4582d8a84be683f9
    Valid from: Tue Aug 21 01:10:46 ACT 2007 until: Tue Aug 21 01:13:59 ACT 2012
    Certificate fingerprints:
             MD5:  D6:56:F0:23:16:E3:62:2C:6F:8A:0A:37:30:A1:84:BE
             SHA1: 73:73:4E:A6:A0:D1:4E:F4:F3:CD:CE:BE:96:80:35:D2:B4:7C:79:C1
    Trust this certificate? [no]:  yes
    Certificate was added to keystore
    

You may now use the 'Secure SSL' option when connecting your application to your directory server.

UNIX

  1. Navigate to the directory in which Java is installed. cd $JAVA_HOME will usually get you there.
  2. Run the command below, where server-certificate.crtis the name of the file from your directory server:

  3. keytool will prompt you for a password. The default keystore password is changeit.
  4. When prompted Trust this certificate? [no]: enter yesto confirm the key import:

    Password:
    Enter keystore password:  changeit
    Owner: CN=ad01, C=US
    Issuer: CN=ad01, C=US
    Serial number: 15563d6677a4e9e4582d8a84be683f9

Mac OS X

  2. Run the command below, where server-certificate.crtis the name of the file from your directory server:

  3. keytool will prompt you for a password. The default keystore password is changeit.
  4. When prompted Trust this certificate? [no]: enter yesto confirm the key import:
