goipa - FreeIPA client library

===============================================================================

GoDoc

goipa is a FreeIPA client library written in Go. It interfaces with the FreeIPA JSON api over HTTPS.

Usage

Install using go tools:

$ go get github.com/ubccr/goipa

Example calling FreeIPA user-show:

package main

import (
    "fmt"

    "github.com/ubccr/goipa"
)

func main() {
    client := ipa.NewDefaultClient()

    err := client.LoginWithKeytab("/path/to/user.keytab", "username")
    if err != nil {
        panic(err)
    }

    rec, err := client.UserShow("username")
    if err != nil {
        panic(err)
    }

    fmt.Println("%s - %s", rec.Username, rec.Uid)
}

Hacking

Development and testing goipa uses docker-compose. The scripts to spin up a FreeIPA test server in docker were copied/adopted from this great repository. Most of the scripts in container/ directory are written by Jan Pazdziora and licensed under Apache 2.0 and modified for use with goipa.

NOTE: The containers are NOT meant to be run in production and used solely for development.

To get started hacking on goipa and running the test suite:

$ cp .env.sample .env
[edit to taste. add passwords and ssh key]

$ docker-compose build
$ docker-compose up -d
$ ssh -p 9022 localhost
$ kinit admin
$ cd /app
$ go test

To run a specific test with trace debugging:

$ go test -v -run UserShow

Functions

func ParseDateTime added in v0.0.6 

func ParseDateTime(str string) time.Time

Parse a FreeIPA datetime. Datetimes in FreeIPA are returned using a class-hint system. Values are stored as an array with a single element indicating the type and value, for example, '[{"__datetime__": "YYYY-MM-DDTHH:MM:SSZ"]}'

Types

type Client 

type Client struct {
	// contains filtered or unexported fields
}

FreeIPA Client

func (*Client) ChangePassword 

func (c *Client) ChangePassword(username, old_passwd, new_passwd, otpcode string) error

func (c *Client) Host() string

Returns FreeIPA server hostname

func (*Client) Login 

func (c *Client) Login(username, password string) error

Login to FreeIPA using local kerberos login username and password

func (*Client) LoginFromCCache added in v0.0.6 

func (c *Client) LoginFromCCache(cpath string) error

Login to FreeIPA using credentials cache

func (*Client) LoginWithKeytab 

func (c *Client) LoginWithKeytab(ktab, username string) error

Login to FreeIPA using local kerberos login with keytab and username

func (*Client) Ping

func (*Client) ResetPassword 

func (c *Client) ResetPassword(username string) (string, error)

func (c *Client) SessionID() string

Return current FreeIPA sessionID

func (*Client) SetAuthTypes

func (*Client) SetPassword 

func (c *Client) SetPassword(username, old_passwd, new_passwd, otpcode string) error

Set user password. In FreeIPA when a password is first set or when a password is later reset it is marked as immediately expired and requires the owner to perform a password change. See here https://www.freeipa.org/page/New_Passwords_Expired for more details. This function exists to circumvent the "new passwords expired" feature of FreeIPA and allow an administrator to set a new password for a user without it being expired. This is acheived, for example, by first calling ResetPassword() then immediately calling this function. *WARNING* See https://www.freeipa.org/page/Self-Service_Password_Reset for security issues and possible weaknesses of this approach.

func (c *Client) StickySession(enable bool)
