Not at all would I have expected this cause when an user complaint today that SSO (Single Sign-on) with the Windows XP operating system ceased working after changing the password.
Investigating the matter it turns out that the user used the colon ‘:’ as part of the password. This and two other special characters (tilde ‘~’ or asterisk ‘*’ on the number pad) are obviously not supported when using SSO between Lotus Notes and the operating system. The issue appears to be well known and documented by IBM. Unfortunately there are currently no plans to address this issue.
Fair enough. At least I know what to tell my users the next time they are running into similar issues.
