title: Atlassian Crowd experiences?
body: <p>we (a team of about 150) are considering moving our ALM solution from Bugzilla/CVS to Jira/svn/Confluence/Bamboo/Fisheye. SO has a lot of good info on those, but I would be interested to learn about another tool from Atlassian - a Single Sign On (SSO) <a href="http://www.atlassian.com/software/crowd/" rel="noreferrer">Crowd</a>, I am considering adding it to the mix for an LDAP integration with our Novell id's.</p>
  
  <ul>
  <li>has someone had any experience with Crowd? </li>
  <li>how does it handle 100/200/500 (after recession, that is) users?</li>
  <li>any tips/tricks?</li>
  <li>would you choose different, open source SSO solutions?</li>
  </ul>
  
  <p>thanks</p>

  <p>EDIT:
  a year has passed...</p>
  
  <p>We got Crowd and went with ActiveDirectory integration along with internal Crowd directory (for short-term contractors, etc.). So far the solution works just great. </p>

  <p>EDIT2:
  Another year: still going strong (We have 1K users now). Nested groups is a killer feature, thankfully it is working fine after last point release. </p>

  <p>EDIT3:
  mid-2012 - 7.5K users - going strong. with a little automation for onboarding (Confluence pages with Ajaxified forms + a little Crowd plugin)</p>
