Managing Your Guest Users on CS Computer Systems

Created August 15, 2017 by Hanz Makmur


Historically, whenever faculty/staff wanted to give "guest users" (visitor, students, alumni, collaborators etc) to access CS systems, they had to contact LCSR System Staff.  Beginning in the Fall 2017, authorized faculty/staff can create a group and sponsor users access to CS computer system without needing to go through LCSR systems staff.  This document shows you how to manage your guest users in a group. If you want a group just to share files, the same tool can be used, but this page is specifically about groups that authorize guest users. 

Please note to simplify the cleanup process, there is a yearly review requirement where group owner is required to review group membership. At this time, 
- the sponsor is sent an email message asking for a yearly review.  
- If there is no response for 2 weeks, a second message is sent.  
- After 2 more weeks with no response, a third message is sent and the group is suspended.  
- Once suspended, group members will get a warning email that his/her account on the cluster specified in the group will be closed within 30 days. In addition, on a specialized system, members will no longer able to login.

To start managing your users and groups simply go to You need to login with your NetID and CS Password. 

Depending on what groups you already own, once login, you may be presented with a list of groups own by you as shown below. 

Different Types of Groups

As shown above, there are 5 different types of groups. 

1. conference is loginable group with no cluster set. Members of this group can't not login to any cluster until cluster is specified.

2. cs211-fall17 is loginable group in yearly review period. If ignored, this group will be suspended as shown on suspended group below.

3. cs211-summer17 is a suspended loginable group needing review. It means member of this group has 30 days before his/her account is closed and one special system, member of the groups can no longer login. This group is suspended because owner of this group did not respond to yearly review email. 4. login-ilab-gpu is loginable group. Members of this group can login to cluster assigned in the group.

4. login-ilab-gpu is an active loginable group. This is a normal loginable group should be.

5. projectA is a filesharing group. Filesharing group allows you to share files or directory to  group.  See  Making a Directory You can Share With Members of your Project for more details.
