ethz_iam_webservice

ETHZ IAM Webservice

Manage users, groups and various services of the ETH Identity and Access Management system (IAM).

Command Line Interface

When installing this module, the iam command is also installed. The basic parameters which are always needed – otherwise they will be asked interactivley – are:

$ iam -u admin-username --password MY-SECRET-PASSWORD

You can also set these environment variables instead:

$ export IAM_USERNAME=admin-username
$ export IAM_PASSWORD=MY-SECRET-PASSWORD

Group CLI

$ iam group --help                           # get extensive help text
# create new group
$ iam group --new id-test-test-01 --ag "ID SIS" -d 'some test description' -t AD -t LDAP ou=AGRL
$ iam group <group-name>                     # info about a group
$ iam group <group-name> -a user1 -a user2   # add new users
$ iam group <group-name> -r user3 -r user4   # remove users

User CLI

Get info about a user, as well as granting/revoking a service or setting its password:

$ iam user --help
$ iam user username
$ iam user username --grant-service LDAPS, -g Mailbox
$ iam user username --revoke-service LDAPS, -r Mailbox
$ iam user username --set-password [-s LDAPS [-s Mailbox]] [--service-password $trengGehe1m]
$ iam user username --init-password   # sets a random initial password for the user

Person

Get info about a person (identity) and its users. You might either provide a username, a NPID or a email address.

$ iam person --help
$ iam person username
$ iam person [e-mail]
$ iam person 123445

Guest

Create guests. For the new guest a new username will automatically be generated. This user gets LDAP and VPN service granted. Because by policy the VPN password needs to differ from the other passwords, the result will present the two initial passwords that are set shortly after creating the guest.

CLI

$ iam guest get <username>
$ iam guest new --help
$ iam guest new -f firstname -l lastname -m [e-mail] -d "my test guest" -h host_username -a "Admingroup Name"
{
    "firstName": "first",
    "lastName": "last",
    "mail ": "[e-mail]",
    "host ": "host_username",
    "respAdminRole ": "Admingroup Name",
    "description": "my test guest",
    "dateOfBirth": "16.06.2000",
    "guestTechnicalContact": "[e-mail]",
    "notification": "To guest and host",
    "hostOrg": "06006",
    "startDate": "16.06.2021",
    "endDate": "16.06.2022",
    "username": "flast",
    "npid": "3210159",
    "init_ldap_password": "xxxxxxx",
}

Default values:

• --technicalContact / -c will default to the email address of the host
• --notification / -n will default to «gh», meaning guest and host will be notified when a guest account expires.
• --startDate / -s is today.
• --endDate / -e is today + 1 year
• --dateOfBirth / -b is today's date in year 2000

Extend guest. After a year, you might want to extend the validity of your guest by another year or by a specific number of months

$ iam guest extend <username>               # will extend the guest by 1 year
$ iam guest extend <username> -m 6          # extend it by today+6 months
$ iam guest extend <username> -e 1.4.2022   # extend it until April 1st. 2022
$ iam guest extend <username> -e 2022-04-01 # same thing, different date format

    members     = ['user1', 'user2']
)

group = e.get_group('groupname')
group = e.get_group(123456)              # gidNumber
group.data                               # all data received from webservice
group.members                            # returns array of usernames or group-names
