Clarify what characters are supported by IBM for use in a Internet/HTTP password
As an administrator you have set up a policy that synchronise your Users Notes and Internet password but find that while the user's can log into their Notes client with their password they cannot log in via a browser with the same password.
Upon investigation it was found that the user had used local punctuation characters in their password.
While local punctuation characters can work as part of a user's Notes password IBM only supports the use of Alphabetic and Printable US ASCII characters, excluding control characters, in an Internet/HTTP password.
It should also be noted that the password cannot begin with a left parenthesis character as mentioned in http://www-01.ibm.com/support/docview.wss?uid=swg21098828
Resolving the problem
Change the user's password to contain only legal characters.
