I want to customize FIM's dialog which is shown when user creates "join group" request. I want that this dialog will looks like one of these: Experts in FIM, is it possible?

Yes, but it is not a very straight forward modification. You cannot modify the existing pages because they are compiled FIM controls. You need to mimic the functionality of the existing controls and add your custom modifications. First, you need to backup and modify the site pages to load an IFRAME pointing to a custom aspx page. Site Pages are located in FEATURES\MSILM2SitePages\aspx\groups [AddMembers.aspx and JoinGroups.aspx] Create your custom aspx pages under your LAYOUTS\custom folder, [AddMembers.aspx and JoinGroups.aspx] These pages will need to read and process the Page Cache properties stored in the object of the CacheID querystring parameter of the Referring Page. Read the "DisplayName", "TypeName" and "Id" properties of the Cache object and use those to build a Put request to the FIM web service. This can be done through the FIM Resource Management Client available on CodePlex here. You'll need to add an Indexed-String attribute to your Group resource to hold the comment text. Create a custom Authorization workflow activity to read the comment text and add it to the Request Details of the Request so it can be displayed to the Approver(s). You can use this to require a comment to be entered. After the Request is Approved, you'll need to add a custom Action workflow activity to clear out the comment attribute on the Group Resource. If you are not looking to get this involved in the inner working of FIM... This exact functionality has already been built and tested.
