What characters are allowed in an Internet/HTTP password

Technote (troubleshooting)


Customers find that when using certain characters as an Internet/HTTP password that they cannot log into Domino via a browser but can log in through their Notes client with the same 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

Resolving the problem

Change the user's password to contain only legal characters.
