Issue Type: Bug Affects Versions: 4.3.0 Assignee: Rod Widdowson ( https://shibboleth.atlassian.net/secure/ViewProfile.jspa?accountId=59fb32bbc24efb3c4ed3c977 ) Components: Attribute Filter Created: 21/Feb/23 7:41 PM Priority: Trivial Reporter: Keith Wessel ( https://shibboleth.atlassian.net/secure/ViewProfile.jspa?accountId=60ad392bb4624d00692388ed )

When an attribute filter returns no values, the message logged is at WARN level. I’ve had these suppressed for a while in my logging config, but another campus asked me about them today, and that’s when I realized they were still there.

2023-02-21 18:30:34,829 - DEBUG [net.shibboleth.idp.attribute.filter.AttributeRule:183] - Attribute filtering engine '/AttributeFilterPolicyGroup:ShibbolethFilterPolicy/AttributeRule:_8378fa026a937803a00d7ff943601d90' Filtering values for attribute 'displayName' which currently contains 1 values

2023-02-21 18:30:34,830 - WARN [net.shibboleth.idp.attribute.filter.AttributeRule:190] - Attribute filtering engine '/AttributeFilterPolicyGroup:ShibbolethFilterPolicy/AttributeRule:_8378fa026a937803a00d7ff943601d90' Filter failed. No values released for attribute 'displayName'

This seems like a rather common situation, and it’s easy to argue that the second message should be logged at DEBUG instead of WARN.
