# check_activesync plugin for Nagios
#
# Originally Written by Kristijan Modric (kmodric_at_gmail.com)
#
# Created: 23 March 2011
#
# Version 1.0 (Kristijan Modric)
#
# Base for this plugin was great article about EAS protocol written by Andreas Helland (Digging Into The Exchange ActiveSync Protocol)
# http://mobilitydojo.net/2010/03/17/digging-into-the-exchange-activesync-protocol/
#
# Command line: check_activesync.sh <Domain> <Username> <Password> <DeviceID> <DeviceType> <ActiveSyncServer> <UniqueFolder>
#
# Description:
# This plugin will attempt to connect to EAS (Exchange Active Sync) server and get Folder information for specific user
# Scripts is checking existing of some unique Folder in the output
#
# Notes:
# - This plugin requires that the curl program is installed.
# - You need to copy binary file activesync.txt to: /usr/lib/nagios/plugins/
# or change in script to reflect your configuration (--data-binary @/usr/lib/nagios/plugins/activesync.txt)
# (If you are interested in the byte sequence here goes: 03 01 6a 00 00 07 56 52 03 30 00 01 01.)
# - You need to configure Active Sync manually to know DeviceID and DeviceType information
# for that you must use real mobile device or emulator to create partnership
# - You need to create unique folder in user's mailbox (eg. Nagios2759671)
# - MS-ASProtocolVersion: 12.0 (Exchange 2007 RTM)
# 14.0 (Exchange 2010)
# 12.1 (Exchange 2007 SP1)
# 12.0 (Exchange 2007 RTM)
#
# Parameters:
# $1 - domain name
# $2 - username
# $3 - password (Note: avoid using of special character e.g.: escalation mark!)
# $4 - DeviceID - A unique id for the device that is synchronizing (you gen retrieve that information from owa (Outlook web access))
# or using power shell:
# Get-ActiveSyncDevice -Identity "user"
# Get-ActiveSyncDevice -Mailbox "domainuser"
# $5 - DeviceType - An id for the device/model you are using, or the ActiveSync client. (can be anything eg. PocketPC or iPhone)
# $6 - activesyncserver (eg. as.contoso.com)
# $7 - UniqueFolder (eg. Nagios2759671)
#
