Sitecore issue – not all users being displayed in the User Manager
I know there more than 15 users should be returned by my providers, but only the first 15 are being displayed in the User Manager.
If I search using a search string such as "a" the results are correctly filtered to those including only "a". Some of the users returned in this result were not displayed in the previous listing. They are valid users and should have appeared when all users were being displayed.
Sometimes the users available shows "Page 1 of 2 (15 of 20 users)". Clicking on the right arrow to view the next page will display a different 15 users and in the bottom right hand corner users available is updated to "Page 2 of 1 (15 items)"
In the release notes for Sitecore,
October 21, 2009
Released Sitecore CMS 6.2.0 rev.091012 (Initial release). Change log. Important Changes:
User Manager
The performance of the User Manager has been improved again after 6.1 Update-1 had removed a previous optimization. This fix will, however, re-introduce the problem that the User Manager in certain situations, for example after creating a new user, will display an incorrect total number of users in the footer.
The Sitecore installation in question is using version 6.1.0 (rev. 090630)
Working theory: we need to update our Sitecore instance.
