Single letter attributes isn't allowed anymore

[tomnil]

In Microsoft Active Directory, the attributes with names "l" and "c" exists but the function "isValidAttributeString" doesn't allow for single letter attribute names. This results in an exeption attribute must be a valid string.

Workaround: In the SearchOptions, use attributes: "*" (this will return the "l" and "c" Attributes).
