Package: debian-edu-config
Version: 2.12.32
Currently authentication of student/teacher users on a workstation does
not work.
Steps to reproduce:
- currently it is not possible to create a student/teacher via gosa due to bugs
#1039698 and #1039699, thus the following example student needs to be
imported into LDAP:
dn: uid=mamus,ou=people,ou=Students,dc=skole,dc=skolelinux,dc=no
sn: Mustermann
givenName: Max
uid: mamus
cn: Max Mustermann
homeDirectory: /skole/tjener/home0/mamus
loginShell: /bin/bash
uidNumber: 1003
gidNumber: 1003
gecos: Max Mustermann
krbPwdPolicyReference:
cn=users,cn=INTERN,cn=kerberos,dc=skole,dc=skolelinux,dc=no
objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: inetOrgPerson
objectClass: gosaAccount
objectClass: posixAccount
objectClass: shadowAccount
objectClass: krbPrincipalAux
objectClass: krbTicketPolicyAux
krbLoginFailedCount: 0
krbTicketFlags: 128
krbPasswordExpiration: 19700101000000Z
dn: cn=mamus,ou=group,ou=Students,dc=skole,dc=skolelinux,dc=no
cn: mamus
description: Gruppe des Benutzers Max Mustermann
gidNumber: 1003
objectClass: top
objectClass: posixGroup
- then the gosa postcreate hook needs to be invoked manually:
sudo /usr/share/debian-edu-config/tools/gosa-create mamus
- afterwards the password needs to be set inside gosa
- finally try to log in as user "mamus" from a workstation
