Class that holds the list of identities (user id's) that should be excluded
from any matching algorithms used when trying to identify account owners
during a reconciliation process. A different list of excluded identities
can be created for each type of service in the system. For example, the
presence of the "root" identity in the exclusion list for the Solaris service
type (profile) will avoid the security problem that can arise if a person
creates an alias called "root" which the system then uses to determine that
they are the owner of the root account on a Solaris system.
isIdentityExcluded(java.lang.String serviceProfileName,
java.lang.String identity)
Returns whether or not a given identity is excluded for a given service
type (profile).
