Configure ISAM plug-in for web servers for use with WAS
ISAM plug-in for web servers can be used as a security gateway for the protected WebSphere Application Server resources.
With such an arrangement the plug-in authorizes all user requests before passing the credentials of the authorized user to WAS in the form of an iv-creds header. Trust between the plug-in and WAS is established through use of basic authentication headers containing the SSO user password.
- The TAM plug-in for web servers configuration shows IV headers configured for post-authorization processing, and basic authentication configured as the authentication mechanism and for post-authorization processing, as shown in the example below.
- After a request is authorized, the basic authentication header is removed from the request (strip-hdr=always) and a new one is added (add-hdr=supply).
- Included in this new header is the password set when the SSO user is created in Create a trusted user account in ISAM.
- Specify this password in the supply-password parameter and it is passed in the newly created header. This basic authentication header enables trust between WAS and the plug-in.
- An iv-creds header is also added (generate=iv-creds), which contains the credential information of the user passed onto WAS. Session cookies are used to maintain session state.
Example
[common-modules]
authentication = BA
session = session-cookie
post-authzn = BA
post-authzn = iv-headers
[iv-headers]
accept = all generate = iv-creds
[BA]
strip-hdr = always
add-hdr = supply
supply-password = sso_user_password
