Compare then use


I have Users in my Active Directory.

I got a made a script that count them and display them on the console with informations about their profile like adresse mail, last time they set their password and when it will expire.

I creat variable for each of thoes informations and now i want to classify my User by the value of when their password will expire.

In order to do it the way i want it, i need that all Users ( for exemple) that have their password that expire in 56 days get grouped, all the Users that have their password expired in 23 days get grouped. Then i want to interract with them by group, like group that have 56 until password expire have a notification for exemple.

What i did is compare the value “password expire in 56 days” and if = 0 then creat a new variable to store them. But doing it this way just give me 2 users and i can’t harvest all of my users that get concerned by the 56 days…

I hope you will understand the message and maybe help me, i keep trying things and will keep until i find a solution !

Cannot understand the question, may be posting the code or a sample you have so far will help in understanding it better.

bit hard to know whats going on, can you show the code please?

I think essentially what you are going to need is to build a hashtable/PSObject from a where-object.

Show the code and people will be able to help.

If you haven’t already please read the bellow post to get an idea as to how to post

You have unnecessarily complicated this.

Why are you not just building collection first and one time only, using the cmdlet that is designed for this…

$Pw23DaysUsers = Search-ADAccount -AccountExpiring -TimeSpan "23"
$Pw56DaysUsers = Search-ADAccount -AccountExpiring -TimeSpan "56"

# Or

$Pw23DaysUsers = Search-ADAccount -AccountExpiring -TimeSpan (New-TimeSpan -Days 23)
$Pw23DaysUsers = Search-ADAccount -AccountExpiring -TimeSpan ([TimeSpan]::FromDays(23))

$Pw56DaysUsers = Search-ADAccount -AccountExpiring -TimeSpan (New-TimeSpan -Days 56)
$Pw56DaysUsers = Search-ADAccount -AccountExpiring -TimeSpan ([TimeSpan]::FromDays(56))

# Or 

$NeverExpires = 9223372036854775807

$ExpringIn = (Get-Date).AddDays(23) 
$Pw23DaysUsers = Get-ADUser -Filter * -Properties accountExpires | 
Where-Object {$_.accountExpires -ne $NeverExpires  -and [datetime]::FromFileTime([int64]::Parse($_.accountExpires)) -lt $ExpringIn }

$ExpringIn = (Get-Date).AddDays(56) 
$Pw56DaysUsers = Get-ADUser -Filter * -Properties accountExpires | 
Where-Object {$_.accountExpires -ne $NeverExpires  -and [datetime]::FromFileTime([int64]::Parse($_.accountExpires)) -lt $ExpringIn }

… then processing that collection?

Each of the above provide a count property. No real reason for the Measure. The above also provides a count and a Length property, that returns the same number, but I can’t see where you need it for your use case.


Or why are you not using:

# get function / cmdlet details
(Get-Command -Name Group-Object).Parameters
Get-help -Name Group-Object -Full
Get-help -Name Group-Object -Online
Get-help -Name Group-Object -Example

… get your groups first, then process the group. Again, this also provides a count property but I can’t se where you need it.

Oh, okay, i see!

I need it to group the mail. Now the script send 1 mail per user so, in my case only 30-40 users’s password reminder. But if someone with 500 user got to received +200 mails per day ( it’s just an exemple) it would be exausted and annoying.

That’s why i wanted to creat groups that have the same amout of time (in days) before the mail.

What you can do is move the Send-MailMessage line to the end of the script, and add $Body to a different variable at that point.

In fact, I’d probably modify the $Body template slightly, start with a header section saying “these are the users who need to change their passwords” or whatever you like, then just add the $name and $messageDays items to it each time, something like $EmailContent += “User: $Name Time: $messageDays”

Then once everything’s been added to it, tack on a brief footer message if you like, and pass that to Send-MailMessage's -Body parameter in the final call.

Okay, i think that what i was trying to do this morning, without succes.

I will try what you said it seems close to the thing i wanted to do!
