Does anyone know how to use password in System.DirectoryServices.ActiveDirectory context. Password is stored in a file.
$UserName="DomainName.com\JohnP"
$PassFile="C:\Temp\Pass.PPP"
$password = get-content $PassFile | ConvertTo-SecureString -AsPlainText -Force
$creds = new-object -typename System.Management.Automation.PSCredential("$UserName",$password)
$a = new-object System.DirectoryServices.ActiveDirectory.DirectoryContext("Forest", "MyForest.com",$UserName,$Password)
It always returns "Server rejected the credentials". If I store password in $Password variable, it works. For example, below code works:
$UserName="DomainName.com\JohnP"
$PassFile="C:\Temp\Pass.PPP"
$password = "MyPassword"
$creds = new-object -typename System.Management.Automation.PSCredential("$UserName",$password)
$a = System.DirectoryServices.ActiveDirectory.DirectoryContext("Forest", "MyForest.com",$UserName,$Password)
Can someone please help as to how to use password from a file and then use with System.DirectoryServices.ActiveDirectory context.
Many thanks!

A [PSCredential] stores the password as a secure string, so it's encrypted.
To get the unencrypted password value:
$creds.GetNetworkCredential().Password

I have two functions, Save Credential to create a .cred file:
$cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList ($Username, $PWord)
$cred.Password | Out-File "some\path\$($cred.Username).cred" -Force
and Get Credential to retrieve the password:
$string = Get-Content "some\path\$($Username).cred" | ConvertTo-SecureString
$cred = New-Object System.Management.Automation.PSCredential -ArgumentList $Username, $string
return $cred
I cannot for the life of me figure out how to retrieve the password from the .cred file that I created. The errors I get are:
ConvertTo-SecureString: Input String was not in the correct format
New-Object: Exception calling .actor with 2 arguments. Cannot process argument because the value of argument "password" is null. change the value of argument password to a non-null value
What version are you bound to? I might not be following properly, but it looks like you don't care about the whole credential and just want the password, so couldn't it just be:
#set
$pwd = "replace me"
$securepwd = $pwd | ConvertTo-SecureString -AsPlainText -Force
$encryptedpwd = $securepwd | ConvertFrom-SecureString
Out-File -FilePath C:\temp\Reference.cred -InputObject $encryptedpwd
then
#get
$securepwd = (Get-Content -Path C:\temp\Reference.cred) | ConvertTo-SecureString
#commented out 3 lines shows how to decrypt in case you want to view it/verify it, but isn't necessary
#$Marshal = [System.Runtime.InteropServices.Marshal]
#$Bstr = $Marshal::SecureStringToBSTR($securepwd)
#$pswd = $Marshal::PtrToStringAuto($Bstr)
#$Marshal::ZeroFreeBSTR($Bstr)
$RunAs = New-Object System.Management.Automation.PSCredential ('Domain\Account', $securepwd)
I'm not as good as most folks on here though, just giving it a stab.
Following the example found here: https://github.com/microsoftgraph/powershell-intune-samples/blob/master/Authentication/Auth_From_File.ps1
More specifically:
$UserPassword = get-Content "$Password" | ConvertTo-SecureString
$userCredentials = new-object Microsoft.IdentityModel.Clients.ActiveDirectory.UserPasswordCredential -ArgumentList $userUPN,$UserPassword
$authResult = [Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContextIntegratedAuthExtensions]::AcquireTokenAsync($authContext, $resourceAppIdURI, $clientid, $userCredentials).Result;
I've tried the following:
$UserPassword = ConvertTo-SecureString -String $Password -AsPlainText -Force
$userCredentials = new-object Microsoft.IdentityModel.Clients.ActiveDirectory.UserPasswordCredential -ArgumentList $userUPN,$UserPassword
$authResult = [Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContextIntegratedAuthExtensions]::AcquireTokenAsync($authContext, $resourceAppIdURI, $clientid, $userCredentials).Result;
However, I've been getting the error that
Authorization Access Token is null, please re-run authentication...
which can be found further in the code.
if($authResult.AccessToken){
[...]
Write-Host
Write-Host "Authorization Access Token is null, please re-run authentication..." -ForegroundColor Red
Write-Host
break
Am I correct in thinking that I probably need to give the password in a different way?
Alright, I think I found whatever went wrong. I tried running another script and had to manually enter the credentials. This prompted me to accept a whole lot of permissions from Microsoft. I think that was the problem. This code now works:
$userId = New-Object "Microsoft.IdentityModel.Clients.ActiveDirectory.UserIdentifier" -ArgumentList ($User, "OptionalDisplayableId")
$UserPassword = ConvertTo-SecureString -String $Password -AsPlainText -Force
$userCredentials = new-object Microsoft.IdentityModel.Clients.ActiveDirectory.UserPasswordCredential -ArgumentList $userUPN,$UserPassword
$authResult = [Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContextIntegratedAuthExtensions]::AcquireTokenAsync($authContext, $resourceAppIdURI, $clientid, $userCredentials).Result;
Still, thank you Mathias and Marc for trying to help :)
I am trying to have my password secured and stored in a file so that I don't need to enter each time when I run the script.
First step, I ran the following, entered the password which got stored into E:\cred.txt file. The txt file now contains an encrypted password.
(Get-Credential).Password | ConvertFrom-SecureString | Out-File "E:\cred.txt"
Secondly, I ran the below Script:
$File = "E:\cred.txt"
$User = "jason#domain.com"
#### I have two different user accounts, one for admin and other for operator,
#### however both user accounts use same password.
$adminuser = $User
$operator = $User -replace "#domain.com"
#### I would need to read $File to get only the password
$pass = New-Object -TypeName System.Management.Automation.PSCredential `
-ArgumentList (Get-Content $File | ConvertTo-SecureString)
$adminuser
$operator
$pass
Output:
jason#domain.com
jason
UserName Password
-------- --------
From the output, it seems New-Object refers to both UserName and Password. And when I try to connect to systems, it fails with Authentication error. Since I already have two different usernames hard coded within the script, how should I get only the password stored in $pass? or is it possible to include all usernames ($User, $adminuser, $operator) into the cred.txt file?
Try this:
#saving credentials
Get-Credential | Export-CliXml -Path c:\credential.xml
#importing credentials to a variable
$Credential = Import-CliXml -Path c:\credential.xml
Or this:
#you could then write it to a file or, i say its a better approach to a registry key
$SecurePassword = ConvertTo-SecureString -String 'P#ssw0rd' -AsPlainText -Force | ConvertFrom-SecureString
#now you are taking it back as a secure string
$RegistrySecureString = $SecurePassword | ConvertTo-SecureString
#you can aslo see the password
$UserName = "NULL"
$Credentials = New-Object System.Management.Automation.PSCredential -ArgumentList $UserName, $RegistrySecureString
$Password = $Credentials.GetNetworkCredential().Password
#P#ssw0rd
I'm having a lot of difficulty with a PowerShell script that I'm trying to call a DirectoryServices query from. Currently, if I do a
$password = read-host "Password" -asSecureString
and subsequently
$credential = New-Object System.Management.Automation.PSCredential $username,$password
everything works fine. However if I try to pass the string parameter with a param($password) and then convert it to a secure string with this code:
$password = ConvertTo-SecureString -AsPlainText -Force $password
After extensive debugging I can see this is working fine in terms of converting the string to a securestring, but I get a bad user/password from DirectoryServices when I use the parameter. Everything works fine when read from the console. Any ideas on what I can do to accept a parameter OR take console input in the absence of a parameter?
This is what I was hoping would work, but doesn't:
if($password -eq $null) {
$password = read-host "Password" -asSecureString
} else {
$password = ConvertTo-SecureString -AsPlainText -Force $password
}
$credential = New-Object System.Management.Automation.PSCredential $username,$password
I recently created a script and was running into the same issue. The work around I found in my case was the following:
#Prompts for the username/password, enter the username in the form of DomainName\UserName
$Credential = get-credential
#Converts the password to clear text to pass it through correctly as passing through a secure string does not work.
$Password = $credential.GetNetworkCredential().password
#Converts the $Credential to just the DomainName/UsernName.
$Account = $credential.UserName
Hopefully this will work in your situation
I'm having some trouble creating a Powershell credential. I am reading an encrypted string from a file, converting the string to a securestring and using that to create the credential. The error I get is:
New-Object : Cannot convert argument "1", with value: "System.Security.SecureString", >for "PSCredential" to type "System.Security.SecureString": "Cannot convert >the "System.Security.SecureString" value of type "System.RuntimeType" to >type "System.Security.SecureString"."
Here is the code I'm using:
$cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList "athenpoly", $(Read-EncString F:\Scripting\1-Dev\RSA\p_ftp_dellpoly.rsa)
Function Read-EncString {
param ([String]$InputFile)
$encrypted = Import-Clixml $InputFile
$key = (3,42,5,77,67,12,76,9,8,9,4,5,6,55,32,81,23,12,3,55,2,9,6,1,5,32,4,55,6,8,56,12)
$csp = New-Object System.Security.Cryptography.CspParameters
$csp.KeyContainerName = "SuperSecretKeyContainer"
$csp.Flags = $csp.Flags -bor [System.Security.Cryptography.CspProviderFlags]::UseMachineKeyStore
$rsa = New-Object System.Security.Cryptography.RSACryptoServiceProvider -ArgumentList 5120,$csp
$rsa.PersistKeyInCsp = $true
$password = [char[]]$rsa.Decrypt($encrypted, $true) -join "" | ConvertTo-SecureString -Key $key
}
Any idea what I am doing wrong?
Here is how I set a credential when reading from a file:
$PassSec = ConvertTo-SecureString $($Pass) -AsPlainText -Force
$Cred = New-Object -TypeName System.Management.Automation.PSCredential -argumentlist $($Domain + "\" + $User),$passSec
Breakdown:
1. $Pass -> Password that is imported (Example: P#ssw0rd)
2. $Domain -> Domain name (Example: Contoso)
3. $User -> User Name (Example: Admin)
What this does is create the variable $cred with the username as Contoso\Admin with a password of P#ssw0rd. This ends up with the same things as the command:
$Cred = Get-Credentials "Contoso\Admin"
Only without the prompt.
