Powershell ActiveDirectory Rename SamAcctName
Posted on 2014-11-14
Hello!
I work on a powershell script for my Active Directory.
My mission is simple: Search every samaccountname contains uppercase and export it to a CSV and then rename the samaccountname in lowercase.
And it work with that code for extract samaccountname in uppercase :
Why "-cmatch'^[a-z A-Z .]+$'"? Cause all of my samaccountname are written like that: x.XXxxx .
Next step, i try to rename in lowercase all the samaccountname in the list of username.csv contained in Active DIrectory.
And i'm blocked with that code :
It doesn't work.
Can you help me? Im a newbie.
The hardest point is after executing that script in powershell, i want to see the result in the AD.
For example: There is an oldSamAccountName: J.smiTH , after executing the script, im able to see in AD (not in the powershell console) the new Account name: j.smith in Properties->Account. Is it possible?
Thanks in advance.

Import-Csv C:\Users\me\username.csv | foreach{Set-ADUser -identity $_-SamAccountName $_.sAMAccountName.tolower()}
You have a - instead of a . listed in this code should be.
Import-Csv C:\Users\me\username.csv | foreach{Set-ADUser -identity $_.SamAccountName $_.sAMAccountName.tolower()}

No, always the error :
In english: A positional parameter cannot be found that accepts argument "me".
I want to be more precise: I want import the samaccountname contained in the csv file, in powershell and for EACH name, apply the function Lowercase to the SamAccountName. And i want to see the result in the AD console when i right click-Properties-Account on the user.
Here my list in the CSV :

t « me ».

First get rid of the " in your CSV file. I have done imports many times and never used quotes in my csv file.
Try this
Import-Csv C:\Users\me\username.csv | foreach {
$samid= $_.samaccountname
$samid=$samid.tolower()
Set-ADUser -identity $_.samaccoutname -samaccoutname $samid
}
Try this
Import-Csv C:\Users\me\username.csv | foreach {
$samid= $_.samaccountname
$samid=$samid.tolower()
Set-ADUser -identity $_.samaccoutname -samaccoutname $samid
}

I tried, but i have this error now :
Translation : impossible to validate an argument on a parameter: identity.
Mhh now i have a doubt about the command: Set-ADUser -identity $_.samaccoutname -samaccoutname $samid.
PS: if i have the " in my csv it's because i opened it with the text editor. Or not? (on my server i can't read csv for the moment.)

samaccoutname should be samaccountname. It is misspelled.
Import-Csv C:\Users\me\username.csv | foreach {
$samid = $($_.samaccountname).tolower()
Set-ADUser -identity $_.samaccountname -samaccountname $samid
}

OK really thank you, it's working... Or not i have not the result i looking for. With screenshot; 
As you can see the SAMACCOUNTNAME is in lowercase as i asked =).
But in AD:
Why it's always t-DESK?
Use another commande like Rename instead "-samaccountname"?
Thank you a lot btw now i understand few more things in powershell.

How many DCs do you have? The info could be changed and may need time to replicate if you have multiple DCs.
Active today
Only two DC. Are you sure this command change the parameter in AD? Cause i always suceed today to made the change in powershell and i got the same problem.
The replication took only 5-10 minutes. I can wait.

Ok ,i did it but no change.
As you can see, when i rename on the AD the user t.desk i have this windows. And this is ALWAYS in t.DESK.

Try this
There might be a better way but it should work.
Import-Csv C:\Users\me\username.csv | foreach {
$samidoriginal = $($_.samaccountname).tolower()
$samid = $($_.samaccountname).tolower()
$samid = $samid + "1"
Set-ADUser -identity $_.samaccountname -samaccountname $samid -UserPrincipalName "$($samid)@contoso.com"
Set-ADUser -identity $samid -samaccountname $samidoriginal -UserPrincipalName "$($samidoriginal)@contoso.com"
}

Wow nice, it work!! But, didn't understand your code yet. I will work on it. Just why $samid +"1" ? And the last line, what did it change in the script?
