UserApplications or a user attribute is an AttributeType with an Attribute Usage Flags of "userApplications".

User attributes are used for actually storing information in the directory, as opposed to OperationalAttribute which are used for storing state information used for internal server processing.

Whenever a SearchRequest does not contain any specific attributes to be returned, then all user attributes in matching entries will be returned.

An explicit value of "*" (the asterisk) may also be included to explicitly include all user attributes.
