## Created by: lucas.cueff[at]lucas-cueff.com
#
## released on 10/2020
#
# v0.5 : first public release - beta version - cmdlets to manage your Azure Active Directory Tenant (focusing on Administrative Unit features) when AzureADPreview cannot handle it correctly ;-)
# Note : currently Powershell Core and AzureADPreview are not working well together (logon / token request issue) : https://github.com/PowerShell/PowerShell/issues/10473 ==> this module will work only with Windows Powershell 5.1
# - cmdlet to get a valid access token (MFA supported) for Microsoft Graph Beta APIs
# - cmdlet to get a valid token for Microsoft Graph API standard / cloud endpoint (ressource graph.windows.net) and be able to use AzureADPreview cmdlets without reauthenticating
# - cmdlet to get all properties available (ex : extensionattribute) for an AAD user account
# - cmdlet to set a web proxy to be used with Use-AzureAD and AzureADPreview cmdlets
# - cmdlet to get all info for current logged in (@ Azure AD Tenant and Graph APIs) AAD user account
# - cmdlet to create / synchronize your on premise Active Directory OUs with Azure AD Administrive Units (not managed currently through Azure AD Connect or other Microsoft cmdlets / modules)
# - cmdlet to add / synchronize your on premise Active Directory users DN with Azure AD Administrative Unit membership (not managed currently through Azure AD Connect or other Microsoft cmdlets / modules)
# - cmdlet to add / remove Azure AD user account in Administrative Unit Role (everything managed in an easy and smooth way including, enabling the AAD role if missing and so on)
# - cmdlet to list all members of an Azure AD Administrative Unit (limited @ first 100 objets with default MS cmdlet... #WTF)
# v0.6 : beta version - focus on Azure AD Connect Cloud Provisionning Tools
# - cmdlet to get your current schema for a specific provisionning agent / service principal
# - cmdlet to update your current schema for a specific provisionning agent / service principal
# - cmdlet to get your default schema (template) for Azure AD Connect Cloud Provisionning
# - cmdlet to get a valid token (MFA supported) for Microsoft Graph API standard / cloud endpoint and MSOnline endpoint and be able to use MSOnline cmdlets without reauthenticating
# v0.7 : beta version - update Administrative Unit features (missing features from Microsoft Cmdlets and new API features)
# - cmdlet to create an Administrative Unit with hidden members
# - cmdlet to get Administrative Units with hidden members
# - cmdlet to create delta view for users, groups, admin units objects
# - cmdlet to get all updates from a delta view for users, groups, admin units objects
# v0.8 : beta version - fix azuread proxy bug when using SSO, add cmdlets to manage Azure AD Dynamic Security Groups
# - fix Set-AzureADproxy cmdlet : not able to set correctly the parameter *ProxyUseDefaultCredentials*
# - new cmdlets to add, get, update Azure AD Dynamic Membership security groups
# - cmdlet to test Dynamic membership for users
# Note : in current release of AzureADPreview I have found a bug regarding Dynamic group (all *-AzureADMSGroup cmdlets). When you try to use them, you have a Null Reference Exception :
# System.NullReferenceException,Microsoft.Open.MSGraphBeta.PowerShell.NewMSGroup
# v0.9 : beta version - add functions / cmdlets related to group and licensing stuff
# - cmdlet to get all Azure AD User with licensing error members of a particular group
# - cmdlet to get licensing info of a particular group
# - cmdlet to add or remove a license on an Azure AD Group
# - cmdlet to get licensing assignment type (group or user) of a particular user
# v1.0 - beta version - add service principal management for authentication and fix / improve code using DaveyRance remark : https://github.com/DaveyRance
# v1.1 - last public release - beta version - update authority URL for Service Principal to be compliant with last version of ADAL library
#
# v1.2 - last public release - beta version - add several functions to be able to manage OU to Admin unit sync in a service principal security context with delegated rights on API (must use MS Graph API only instead of mixing Azure AD Graph and MS Graph APIs) :
# - update Sync-ADOUtoAzureADAdministrativeUnit
# - update cmdlet Sync-ADUsertoAzureADAdministrativeUnitMember
# - update cmdlet Get-AzureADUserCustom (Get-AzureADUserallproperties)
# - add cmdlet Get-AzureADServicePrincipalCustom
# - add cmdlet Get-AzureADAdministrativeUnitCustom
# - add cmdlet Add-AzureADAdministrativeUnitMemberCustom
# - add cmdlet New-AzureADAdministrativeUnitCustom (New-AzureADAdministrativeUnitHidden)
# - add cmdlet Watch-AzureADAccessToken (be able to watch and auto renew Access Token of a service principal before expiration - useful in a script context when operation can take more than one hour)
# - update cmdlet Set-AzureADProxy (add bypassproxy on local option)
