ADComparisonAttribute only Supports Single Value AD attributes

Symptoms

ADComparison predicate could only support single value attribute which caused the following scenario not possible: "mail is only allowed between the sender and a recipient if they share a common entry in a specified AD attribute"

Resolution

ADComparisonAttribute can now support multi value AD attributes

More Information

A design change to support multi value attribute in ADComparison predicate has been implemented.

The attribute property is split into separate values (delimited by semi-colons) and placed into an array. A string comparison is done on each value in one array with each value in the other array. The comparison is case-insensitive. It is possible to have an array with length = 1, if there is no delimiter.

The return value is true if any value in the first array matches any value in the second array.

Examples of comparison scenarios with return results:

Sender’s customattribute1Recipient’s customattribute1 Result
"value1;value2" "value3;value4" Not equal because none of the strings match.
"value1;value2" "VALUE2;VALUE3"Equal. Comparisons are case insensitive.
"value1;value2" "value1"Equal. It is still valid to have no delimiter.
"value1" "value1"Equal. It is still valid to have no delimiter in either for this case.
"value1;value2" "value2;value3"Equal, value2 is a match.

Notes:


  • No new exception generated by this change.
  • Since the semi-colon is used as a delimiter, it is possible to obtain unintended results if there are properties that use semi-colons that aren’t intended as delimiters. If the attribute contains a semi-colon, it will be split into separate strings, each of which will be compared individually.
  • Custom attribute is limited by its overall size. It can accommodate up to 2K characters.
  • The following parameters are not affected by this change:
    • ADComparisonOperator
    • ExceptIfADComparisonAttribute
    • ExceptIfRecipientADAttributeMatchesPattern
