1 How To for users

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

Gruppe Prof. Krivobokova: Hr. Stefan Geissler (stefan.geissler@univie.ac.at)
Gruppe Prof. Cuchiero: Hr. Guido Gazzani (guido.gazzani@univie.ac.at)
Gruppe Prof. Ehmke: Hr. Rico Kötschau (rico.koetschau@univie.ac.at)
Gruppe Prof. Dörner: Roland Braune, Georg Fröhlich (georg.erwin.adrian.froehlich@univie.ac.at)
Gruppe Operations Research: Michael Kahr (m.kahr@univie.ac.at)

2.3 Step by Step

Group admin is within the university's network.

If you want to test a bit, ag_testAG_ou is the playground to do so.

• 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
