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.

2.3 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

you might want to change your password.

• Group Admin can connect herself via ssh as well:

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

here you can check if the uid, /home/xyz userdirectory, for the new user you want to create is really unique! (If you would assign some attribute breaking the uniqueness, the web-interface should throw an ERROR anyway.)
