Login problems with AD useraccounts when the username contains special characters

Hi,

We encounter login problems with  AD user-accounts when the username contains special characters like é or ü ......users cannot login! Hope someone has a solution because the 1500 user-account are imported!

Thanks!

Kind regards,

Please see the Microsoft link below:

The diacritic mark is not supported for user names (AD should have just change the diacritic to the normal letter), however you may try to have the user sign in without it:
e.g
stéinr  could probably login as steinr
CLR Benjamin

Maybe i have a solution.

Go to powershell with AD module write this command:
Get-ADUser -filter * -Searchbase 'OU=your1500users,DC=contoso,DC=com' | ? {$_.sAMAccountname -cmatch'[é ü ]'}  | Select sAMaccountname | Export-csv -path C:\username.csv -NTI

Open in new window


Then go to your csv, copy the column A ( ctrl+c ,on excel). Replace every é by e, ü by u (CTRL+F -> replace -> search é and replace with E...) on the column A . Rename A1 by samaccountname1.
Then paste the original A column on B. Save your CSV.

Then execute this powershell script:

Import-Csv C:\username.csv | foreach {
$samoriginal = $($_.samaccountname)
$samnew = $($_.samaccountname1)
$samnew1 = $samnew + "1"
Set-ADUser -identity $samoriginal -samaccountname $samnew1 -UserPrincipalName "$($samnew1)@contoso.com"
Set-ADUser -identity $samoriginal -samaccountname $samnew -UserPrincipalName "$($samnew)@contoso.com"
}

Open in new window


This code will change the sam account name and UPN.
I don't know if it works. If an expert understood what i mean, can you correct me?
