2 How To for Group Admins
Groups are independently administered by their group admins. To indicate the group-spaces, the User-IDs (uid) are the Group IDs (gid) plus some addition.
2.1 Specs

2.3 Step by Step
Group admin is within the university's network.
- Group Admin can reach the admin interface: https://hpc3.wiwi.univie.ac.at
- Group Admin can log into the Web-Interface , e.g.
uid=ag_ha-loibl,ou=ag_hautsch_ou,ou=People,dc=hpc,dc=wiwi,dc=univie,dc=ac,dc=at password 12345
If you might want to change your password, click your uid:
- Connect via ssh:
ssh ag_ha-loibl@hpc3.wiwi.univie.ac.at
- Within this ssh session, Group admin can access OpenLdap directory entry (not the local /etc/passwd!)
getent passwd | grep ag-XY
If you assigned an uid of 9001, 9002, or 9003 to a new user, or /home/ag_te-testuser-1 as a home directory, or use a username of ag_te-testuser-1, then you would clearly violate the uniqueness, because all these attributes have already been used.
- go to blueprint user
- Copy blueprint user to newuser
- Fill in attrinutes for new user
- Check on new user and submit
- OOps! Attribute (uid=9003 was not unique); Error message
- Make attribute unique (uid=9004)
- Success!
- the researcher can now log in the web-interface and change her password.
- the researcher can now ssh to hpc3.
- the researcher can transparently access the fat but a bit slower storage via
cd /ag_YOUR-GROUP
