When editing a user from the Participant Administration utility, you can change the user password along with changing other user information if you have the rights needed to make changes in the directory service.

When you change the password for a user, the old password may still be active for a period of time. This is the case if the web server you are using caches user information, as is true with the Apache web server. If a user password is changed in LDAP, there may be a short period of time where the new password will not work, or where the old password and the new password will both work due to the cache. This is only temporary and will resolve itself when the web server cache expires and the web server refreshes the LDAP information. Generally, the time to live for cache entries is short. For example, the default for Apache is 10 minutes.

Additionally, you can configure your Windchill solution so that users can change their own passwords.
