Problem
Atlassian Crowd is a great login and user identity system, with a (relatively) easy SSO setup (especially for other Atlassian apps).
Crowd can also be used to reset user passwords and send the user an email with a password reset link. However, confusingly after a successful password reset/update the user gets dumped to the Crowd login page. Now, Crowd is a user/identify management system so normal users (i.e. non-crowd admins) can't actually login. What it should do is redirect the user to another login page (e.g. confluence, or another app) on a successful password reset.
Solution
An easy solution here is to use your web-server of choice (Apache, nginx, ...) to redirect to another site/login-page on the URL query string ?passwordUpdateSuccessful=true.
I use Apache2 and outline it's use specifically for Atlassian web apps here. Below is part of my VirtualHost config for Crowd, with a RewriteRule to redirect to my confluence instance's login page (see lines 10-12):
<VirtualHost *:443>
ServerName crowd.jaytaala.com
ProxyRequests Off
ProxyVia Off
ProxyPreserveHost On
RewriteEngine On
# redirect to confluence when passwordUpdateSuccessful=true
RewriteCond %{QUERY_STRING} passwordUpdateSuccessful=true
RewriteRule ^(.*)$ https://confluence.jaytaala.com/login.action? [R,L]
RewriteCond %{REQUEST_URI} !^/crowd/ [OR]
RewriteCond %{REQUEST_URI} about.jsp$
RewriteRule ^(.*)$ http://127.0.0.1:8095/crowd/ [P,L]
ProxyPass / http://127.0.0.1:8095/
ProxyPassReverse / http://127.0.0.1:8095/
...
</VirtualHost>
Lines 10-12 show the redirect when the URL looks like ...?passwordUpdateSuccessful=true. So as soon as the password update/reset is completed successfully, Apache will redirect to my confluence login page (the final ? removes the query string "passwordUpdateSuccessful=true" on the redirect.
Lines 14-16 are optional and used to redirect all root requests to the /crowd/ context (see Redirecting Crowd root requests to crowd context - skip landing page).
