I've decided to write a small cheatsheet for user- and group-.management in FreeIPA. User-management Add user: [archy@ipa01 ~]$ ipa user-add $username --first=user --last=name --shell=/bin/bash --homedir=/home/username --email=username@archyslife.lan --password Modify user: [archy@ipa01 ~]$ ipa user-mod $username --help The options for user-mod and user-add are exactly the same. Change user's password: [archy@ipa01 ~]$ ipa user-mod $username --password Delete user: [archy@ipa01 ~]$ ipa user-del $username Add user to group: [archy@ipa01 ~]$ ipa group-add-member group --users=$username Remove user from group: [archy@ipa01 ~]$ ipa group-remove-member group --users=$username List users: [archy@ipa01 ~]$ ipa user-find Show information to a specific user: [archy@ipa01 ~]$ ipa user-show $username Disable a user-account: [archy@ipa01 ~]$ ipa user-disable $username Enable a user-account: [archy@ipa01 ~]$ ipa user-enable $username

This can be fixed by running [archy@spacewalk ~]$ sudo spacewalk-service stop && sleep 5 && spacewalk-service start The services should now be in r
