 ### -Partition
-The default authentication method is Negotiate.
+Specifies the distinguished name of an Active Directory partition.
+The distinguished name must be one of the naming contexts on the current directory server.
+The cmdlet searches this partition to find the object defined by the **Identity** parameter.
 
-A Secure Sockets Layer (SSL) connection is required for the Basic authentication method.
+In many cases, a default value is used for the **Partition** parameter if no value is specified.
+The rules for determining the default value are given below.
+Note that rules listed first are evaluated first and once a default value can be determined, no further rules are evaluated.
+
+In Active Directory Domain Services (AD DS) environments, a default value for **Partition** is set in the following cases: 
+
+- If the **Identity** parameter is set to a distinguished name, the default value of **Partition** is automatically generated from this distinguished name.
+- If running cmdlets from an Active Directory provider drive, the default value of **Partition** is automatically generated from the current path in the drive. 
+- If none of the previous cases apply, the default value of **Partition** is set to the default partition or naming context of the target domain.
+
+In Active Directory Lightweight Directory Services (AD LDS) environments, a default value for **Partition** is set in the following cases:
+
+- If the **Identity** parameter is set to a distinguished name, the default value of **Partition** is automatically generated from this distinguished name. 
+- If running cmdlets from an Active Directory provider drive, the default value of **Partition** is automatically generated from the current path in the drive. 
+- If the target AD LDS instance has a default naming context, the default value of **Partition** is set to the default naming context.
+To specify a default naming context for an AD LDS environment, set the **msDS-defaultNamingContext** property of the Active Directory directory service agent object (**nTDSDSA**) for the AD LDS instance. 
+- If none of the previous cases apply, the **Partition** parameter does not take any default value.

 ### -ResourceContextPartition
 Specifies the distinguished name of the partition of an AD or AD LDS instance to search.
 Use this parameter with the *ResourceContextServer* parameter to specify a partition hosted by the specified server.
