© 2013 IBM Corporation Rational Services - ISSR 3 LDAP basics  LDAP: Lightweight Directory Access Protocol, an industry standard for storing and retrieving attributes of things (or people)  LDAP uses TCP ports 389 (insecure) and 636 (secure) by default  Directories typically have a hierarchical structure  Every directory entry has one or more attributes, each of which has one or more values  Every entry has a name that is unique across the directory, its Distinguished Name (DN)

© 2013 IBM Corporation Rational Services - ISSR LDAP and CLM 8 Specify the connection information for the LDAP server. To use LDAP over SSL, use ldaps:// instead of ldap:// Specify the DN of the LDAP account used to search the directory (aka “Bind DN”). This is typically required by Active Directory but any LDAP server can require it. Specify the password of the Bind DN above

© 2013 IBM Corporation Rational Services - ISSR LDAP and CLM (continued) 9 Specify the Base DN that contains all users who are going to be able to log into CLM Specify which attributes in the LDAP entry for a user map to the corresponding properties in a CLM user record.

© 2013 IBM Corporation Rational Services - ISSR LDAP and CLM (continued) 10 Specify the Base DN that contains all groups that you are specifying in the field below Specify which LDAP groups map to the five Jazz system groups. If the LDAP group names match the Jazz group names, the default can be kept. Specify which attribute of the group entry in LDAP contains the name of the group. Specify which attribute of the group entry in LDAP contains the members of the group.

For performance reasons choose the lowest point in the hierarchy that is high enough to contain all users/groups who need access to CLM as the Base DN.

© 2013 IBM Corporation Rational Services - ISSR Testing the LDAP configuration 12 Enter the user ID of an LDAP-authenticated user that will have administrative privileges to continue to the setup. This user must be member of the LDAP group mapped to JazzAdmins. Note: “user ID” refers to the LDAP attribute that was configured to map to the “userId” property in Jazz.

© 2013 IBM Corporation Rational Services - ISSR Importing Users 14 In order for users to be able to log into CLM, they must be imported into the Jazz repository. You can search for users using the Import Users wizard. The asterisk (*) is available as a wildcard. Users are synced nightly with the LDAP server, so users added in LDAP will be created in CLM by the next day. (You can also trigger the sync manually at any time.)

© 2013 IBM Corporation Rational Services - ISSR Troubleshooting basic LDAP problems  LDAP configuration is complete but the Import Users wizard shows no users –Use an LDAP management tool to verify that the Base DN for users and the search string are correct and make changes as necessary  A user does not have JazzAdmin privileges even though that user is member of the corresponding group in LDAP –Verify that the Jazz group-to-LDAP group mapping is correct –Verify that the correct LDAP attribute was selected as the one containing membership information –Verify that the Base DN for groups is correct and use an LDAP management tool to verify the group can be found –If the user has a mixed-case username or entered their username with a different case than what is stored in LDAP, make sure that case insensitive user matching is enabled. This is a setting that is configurable on the Advanced Properties page in JTS. 16
