Sorting groups and users based on the column

Summary

At the moment the user list(Administration > Accounts > Users) and group list(Administration > Accounts > Groups) are sorted by default hard settings. The search provide a specific search result. It is tedious to perform a specific search when a group or username is hard to recall, the sorting option would east the search process.

Expected Results

It would best fit on sorting the user list and group list base on the available columns:

• Name(applicable for group list as well)
• Username
• Email
• Directory
• Last authenticated

Actual Results

Unable to sort the user and group list which require manual searching.
