We have implemented AD integration through ServiceLink in our Development and Testing environment. We have developed a webservice which interacts with Active Directory and we are using HTTP agent and HTTP adapters to call this webservice through servicelink. Let me know if you need more details on this.
We are just beginning proof of concepts with Active Roles integration (managing AD objects) using Quest Active Roles SPML provider. Has anyone else used this? We are using the custom HTTPIWA2 adapter (until we upgrade to newscale 9) doing webservice calls. I'm particularly interested in snippets of XSLT code to transform the inbound message from Active Roles.
