Filter to insert a subject-id that complies with the SAML V2.0 Subject Identifier Attributes Profile.
This filter will take an attribute and a scope as input and transforms this into a scoped identifier that is globally unique for a given user.
If privacy is of your concern, you may want to use the PairwiseID-filter instead.
Note:
Since the subject-id is specified as single-value attribute, only the first
value of identifyingAttribute
and scopeAttribute
are considered.
'authproc' => [
50 => [
'class' => 'subjectidattrs:SubjectID',
'identifyingAttribute' => 'uid',
'scopeAttribute' => 'scope',
],
