function New-Session { <# .SYNOPSIS Create new session .DESCRIPTION Create a new TssSession for working with a Secret Server .EXAMPLE $cred = [PSCredential]::new('apiuser',(ConvertTo-SecureString -String "Fancy%$#Passwod" -AsPlainText -Force)) New-TssSession -SecretServer https://ssvault.com/SecretServer -Credential $cred A PSCredential is created for the apiuser account. The internal TssSession is updated upon successful authentication, and then output to the console. .EXAMPLE $token = .\tss.exe -kd c:\secretserver\module_testing\ -cd c:\secretserver\module_testing $tssSession = New-TssSession -SecretServer https://ssvault.com/SecretServer -AccessToken $token A token is requested via Client SDK (after proper init has been done) TssSession object is created with minimum properties required by the module. Note that this use case, SessionRefresh and SessionExpire are not supported .EXAMPLE New-TssSession -SecretServer https://ssvault.com/SecretServer -Credential (Get-Credential apiuser) A prompt to enter the password for the apiuser is given by PowerShell. Upon successful authentication the response from the oauth2/token endpoint is output to the console. .EXAMPLE $secretCred = [pscredential]::new('ssadmin',(ConvertTo-SecureString -String 'F@#R*(@#$SFSDF1234' -AsPlainText -Force))) $session = nts https://ssvault.com/SecretServer $secretCred Create a credential object Use the alias nts to create a session object .EXAMPLE $session = nts https://ssvault.com/SecretServer -UseWindowsAuth Create a session object utilizing Windows Integrated Authentication (IWA) Use the alias nts to create a session object .LINK https://thycotic-ps.github.io/thycotic.secretserver/commands/New-TssSession .OUTPUTS TssSession. #> [cmdletbinding(SupportsShouldProcess)] [OutputType('TssSession')] param( # Secret Server URL [Parameter(Mandatory,ParameterSetName = 'new', Position = 0)] [Parameter(Mandatory,ParameterSetName = 'sdk', Position = 0)] [Parameter(Mandatory,ParameterSetName = 'winauth', Position = 1)] [Parameter(Mandatory,ParameterSetName = 'clientSdk')] [uri] $SecretServer, # Specify a Secret Server user account.
