+# Unix Group Management
+
+Users can be added to a unix group by this workflow:
+[SSH Gateway - User Guide](https://linux.psi.ch/services-user-guide/unix_groups.html)
+
+The administrators registered for a group will get an approval request email. Uppon approval the user will be automatically added to the group.
+
+You can also add users on their behalf. If you are one of the admins of the groups the request will be automatically approved (no need to approve it additionally)
+
+
+The member as well as the administrators of the group can be found here: 
+https://psi.service-now.com/now/nav/ui/classic/params/target/sys_user_group_list.do%3Fsysparm_userpref_module%3D92f011c81b440690d6a82f4aab4bcb5f%26sysparm_view%3Dlinux_groups%26sysparm_query%3DnameSTARTSWITHunx%255Eactive%253Dtrue%255EEQ%26sysparm_force_row_count%3D500
+
+![](unix_group-01.png)
+
+If there are no administrators marked, the helpdesk will get the approval request.
+
+To remove users from a group create a general Service Now ticket.
+(there will be an easier workflow in the upcoming weeks)
