If you read the blog before you should know that I am a big fan of automating repetitive admin tasks.  Currently I am building an Ivanti Identity Director environment. Part of onboaring a new employee in this environment is enabling Skype for this new AD account.

To perform this task in Powershell I wrote the following script, which I execute in Ivanti Automation.

[sourcecode language='powershell'  padlinenumbers='true']
##################################
 # Enable Sykpe User
 ##################################
 # Created by R. Plomp 20-6-2019
 # Version 1.0
 ##################################

$SAM = $[UserLogonName]
 $SMTP = $[Primary E-mail address]
 $SIP = sip:+$SMTP
 $Pool = $[RegistrarPool]

# Import Skype for Business Module
 Import-Module C:\Program Files\Common Files\Skype for Business Server 2015\Modules\SkypeForBusiness\SkypeForBusiness.psd1

# Enable Skype
If (Get-CsUser -Identity $SMTP -ErrorAction SilentlyContinue)
     {
     Write-Host Skype User does exists
     }
 Else
     {
     Enable-CsUser -Identity $SMTP -SipAddress $SIP -RegistrarPool $Pool
     Write-Host Skype User created
     }
[/sourcecode]

When I ran this script with my standard Ivanti Admin account I received the following error:

Error: Enable-CsUser : Cannot open database “xds” requested by the login. The login failed. Login failed for user ‘…’.

The user mentioned in the error message is the Ivanti Admin that I use the execute all tasks within Ivanti Automation.
While researching this error I came to the following solution, the Ivanti Admin account should me a member of the CsAdministrator, and the RTCUniversalServerAdministrator AD Group.
