Description

The New-MsolServicePrincipalCredential cmdlet adds a new credential to a service principal or adds or rolls credential keys for an application. The service principal is identified by supplying either the object ID, app principal ID, or service principal name (SPN).

Examples

Example 1: Add an existing credential to a service principal

PS C:\> $Certificate = New-Object System.Security.Cryptography.X509Certificates.X509Certificate
PS C:\> $Certificate.Import("C:\myapp.cer")
PS C:\> $BinCert = $Certificate.GetRawCertData()
PS C:\> $CredValue = [System.Convert]::ToBase64String($binCert);
PS C:\> New-MsolServicePrincipalCredential -ServicePrincipalName "MyApp/myApp.com" -Type asymmetric -Value $CredValue -StartDate $Certificate.GetEffectiveDateString() -EndDate $Certificate.GetExpirationDateString()

This example adds a credential, or a key, object to an existing service principal. In this example, the supplied base64 encoded public X509 certificate, named myapp.cer, is added to the service principal using the service principal name value of MyApp/myApp.com.

Example 2: Register an on-premises Exchange Server

PS C:\> New-MsolServicePrincipalCredential -AppPrincipalId  -Type asymmetric -Value $CredValue

This command registers an on-premises Exchange Server so that communications between the Exchange Server and Microsoft Azure Active Directory services such as Office 365 can occur. This example assumes that $credValue contains the base64 encoded public X509 certificate used to represent the on-premises Exchange server. The well known IDs for Office 365 servers are:

• Exchange: 00000002-0000-0ff1-ce00-000000000000
• SharePoint: 00000003-0000-0ff1-ce00-000000000000
• Lync: 00000004-0000-0ff1-ce00-000000000000

Parameters

-AppPrincipalId

Specifies the application ID of the service principal to which to add the credential.

Type:	Guid
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-EndDate

Specifies the effective end date of the credential usage. The default value is one year from today. For an asymmetric type credential, this must be set to on or before the date that the X509 certificate is valid until, otherwise an OAuth token will not be issued for this application.

Type:	DateTime
Position:	Named
Default value:	Today + 1 year
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-ObjectId

Specifies the unique object ID of the service principal to which to add the credential.

Type:	Guid
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-ServicePrincipalName

Specifies the name of the service principal to which to add the credential. An SPN must use one of the following formats:

• appName
• appName/hostname
• a valid URL

AppName represents the name of the application. Hostname represents the URI authority for the application.

Type:	String
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-StartDate

Specifies the effective start date of the credential usage. The default value is today. For an asymmetric type credential, this must be set to on or after the date that the X509 certificate is valid from, otherwise an OAuth token will not be issued for this application.

Type:	DateTime
Position:	Named
Default value:	Today
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-TenantId

Specifies the unique ID of the tenant on which to perform the operation. The default value is the tenant of the current user. This parameter applies only to partner users.

Type:	Guid
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-Type

Specifies the type of credential used. Valid values are:

• asymmetric
• symmetric
• password

The default value is symmetric.

Important

Asymmetric keys are recommended. Symmetric keys aren't secure and will be disabled for service principals that access Microsoft first-party applications.

Type:	ServicePrincipalCredentialType
Position:	Named
Default value:	Symmetric
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-Usage

Specifies the usage of the credential key. The credential key usage can either be set to sign or verify a token. The default value is verify. Sign is allowed ONLY for symmetric keys. Verify is allowed for all key types.

A verify credential key is required by the Azure Active Directory directory to verify that the request token was sent by your application, which is represented by this service principal.

Your application may optionally require that Azure Active Directory services issue tokens to your application signed with your signing key rather than the asymmetric public key identifying Microsoft Azure Active Directory. In this case, provide a sign credential key for your service principal.

Type:	ServicePrincipalCredentialUsage
Position:	Named
Default value:	Verify
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-Value

Specifies the value of the credential.

• If the credential type is asymmetric, the value represents the base 64 encoded certificate.
• If the credential type is symmetric and the Value parameter is not specified, a 256 bit AES key is automatically created and valid for one year from creation.
• If the credential type is password, specify Value. It should not be base 64 encoded.

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False
