FreeIPA

Introduction

FreeIPA is the integrated security information management solution used at the Hackerspace Gent.

It uses a combination of 389 Directory Server (LDAPv3), MIT Kerberos, NTP (optional), DNS (optional), and DogTag (Certificate System).

Access

URL: https://ipa.hackerspace.gent

First time access: You will be prompted for a new password. Don't forget to set your correct email address.

Management

Allow users to modify their own email (or some other fields)

IPA Server > Self Service Permissions > Add

Self-service name: "Users can manage their own email address"
Attributes: mail

Hooking up services to LDAP for authentication

Creating a normal user is highly discouraged. Create dedicated system accounts which are only allowed to bind.

You will need to connected directly via LDAP to make the appropriate changes.

[root@ipa ~]# ldapmodify -x -D 'cn=Directory Manager' -W
Enter LDAP Password:
dn: uid=<application account name>,cn=sysaccounts,cn=etc,dc=hackerspace,dc=gent
changetype: add
objectclass: account
objectclass: simplesecurityobject
uid: <application account name>
userPassword: <password for the application>
passwordExpirationTime: 20380119031407Z
nsIdleTimeout: 0
<blank line>
^D

Example of configuration:

URL             ldap://ipa.hackerspace.gent:389
BindDN          "uid=<application account name>,cn=sysaccounts,cn=etc,dc=hackerspace,dc=gent"
Password        "<password for the application>"

BaseDN          "cn=users,cn=accounts,dc=hackerspace,dc=gent"
SearchFilter    "(uid=%u)"

BaseDN          "cn=groups,cn=accounts,dc=hackerspace,dc=gent"
SearchFilter    "(member=%g)"

STARTTLS

If you want to use STARTTLS for securing the connection between the application and LDAP, you can use the CA Certificate:
