6
7 DigDash Enterprise allows the creation of a single DigDash information flow for all users existing in a Cognos namespace. The {{glossaryReference glossaryId="Glossary" entryId="Flux"}}Flow{{/glossaryReference}} displays data specific to each user using the security settings defined in Cognos.

13 = Preparing the Cognos server =
14
15 To enable DigDash Enterprise to obtain information from your Cognos 8 server, the first step is to establish a link between the two servers.
16
17 To do this, a DigDash authentication plug-in must be deployed on your Cognos server. You must also define a global password to enable the link between the two servers.
18
19 Authentication from DigDash Enterprise will be done using the name of one of the Cognos users present in a specific namespace, the password to be used being the shared password (and not the user's password).
20
21 Here are the detailed steps.
22
23 == Preparing to set up single sign-on ==
24
25 The authentication plug-in will be sent to a specific namespace, for example your LDAP namespace. Retrieve the identifier of this namespace from the Cognos configuration console:
26
27 1. Start **IBM Cognos Configuration**
28 1. Select **Security**
29 1. Select **Authentication**
30 1. Select the desired namespace
31 1. Note the value of the **namespace identifier** field
32 1. Choose a shared password
33
34 == Create the configuration files ==
35
36 1. Start a DOS console and go to the **<DDE install>/add-ons/cognos** folder
37 1. Type the command line: **java -jar** **tsap_configurator.jar**
38 1. **Enter Authorization namespace** is displayed. Press **Enter**.
39 1. An **Enter Authorization namespace** line appears. Enter the name you wrote down in step 1
40 1. **Create global password for DigDash** is displayed. Enter the password you wish to use
41 1. Enter the same password again.
42 1. A **Configuration file successfully created** message is displayed. A **ddauth4Cognos.properties** file containing the namespace name and global password has been created.
43
44 == Copy the authentication files to your Cognos server ==
45
46 1. Copy the **digdash_cognos.jar** file to the directory:
47 **<Program Files>/cognos/c8/webapps/p2pd/WEB-INF/lib**
48 1. Copy the file **ddauth4cognos.properties** into the directory:
49 **<Program Files>/cognos/c8/webapps/p2pd/WEB-INF/classes**
50 1. Restart Cognos
51
52 == Configure the authentication plug-in in Cognos ==
53
54 1. Start IBM Cognos Configuration
55 1. Select **Security**
56 1. Select **Authentication**
57 1. Add a new namespace (right-click on **Authentication**, then select **New resource and Namespace**)
58 1. Choose a name for this new namespace
59 1. From the Type drop-down list, select **Custom Java Provider**.
60 1. In the **Resource Properties** panel, change the value of the **Java Class Name** field to **com.digdash.cognos.TSAP.DDTrustedSignon**
