These are the steps i follow to integrate with any web app using ca pam browser.
1) Check if the web page works using Chrome without the need for loading java/adobe plugins.
If yes then most likely it will work with Ca pam browser too.
2) Configure device/Services , accounts and policy , Perform learn mode and save.
3) in the policy do not specify account for auto login, try to launch the application from the ca pam and enter the credential manually. If you are logged in successfully then next time specify the accounts in the policy.
Basically step 3 is to ensure that auto login works with ca pam accounts and you can eliminate account related issues there.
Often there are times when the application expects additional information apart from username/password and submit button , like for example in your case IP address in the first text box and may be(domain/host name in the last list box at the end, If those settings are not set by default in the login page by the application then it may not work.)
