PI48578: CWWSS8014E error in SAML Web SSO can be misleading

Fixes are available

APAR status

Closed as program error.

Error description

You can get the CWWSS8014E error message in SAML Web SSO when
the DN of the signer certificate that signed the SAML
assertion does not match sso_<id>.idp_<id>.allowedIssuerDN.

CWWSS8014E: The Issuer name in the SAML Assertion is not
trusted.

This message implies that the Issuer element in the SAML
Assertion is incorrect, not that the signer certificate is
incorrect.

****************************************************************
The SAML Web Single Sign-On CWWSS8014E error shown below can be
misleading:
CWWSS8014E: The Issuer name in the SAML Assertion is not
trusted.
You can get this error for the following reasons:
1) The Issuer element in the SAML Assertion does not match the
value configured for the sso_<id>.idp_<id>.allowedIssuerName
TAI custom property.
2) The DN of the signer certificate does not match the value
configured for the sso_<id>.idp_<id>.allowedIssuerDN TAI custom
property.
3) A value is configured for the
sso_<id>.idp_<id>.allowedIssuerDN TAI custom property but, at
the time the Issuer validation is being performed, the signer
certificate for the SAML Assertion is not available.

Problem conclusion

The SAML Web Single Sign-On TAI is updated to emit more
detailed messages.

To CWWSS8014E, an insert is added to indicate the Issuer name
that is in the SAML Assertion that failed validation:

CWWSS8014E: The Issuer name in the SAML Assertion is not
trusted. [{0}]


When the signer certificate of the SAML Assertion does not
match allowedIssuerDN, the following message will be emitted:

CWWSS8042E: The Subject DN of the signer certificate in the
SAML Assertion is not trusted: [{0}]


When there is a value configured for allowedIssuerDN and the
signer certificate of the SAML Assertion is not available at
the time the Issuer validation is performed, one of the
following messages will be emitted:

1) If the sso_<id>.sp.wantAssertionSigned TAI custom property
is set to true, the following message will be emitted:

CWWSS8042E: The Subject DN of the signer certificate in the
SAML Assertion is not trusted: []

Also, if com.ibm.ws.security.web.* trace is enabled, the
following entry will be in the trace:

Unable to evaluate trusted Issuer Subject DN because the
signer certificate is not available.


2) If the sso_<id>.sp.wantAssertionSigned TAI custom property
is not set to true, the following message will be emitted:

CWWSS8043E: The allowed issuer validation failed for the
certificate Subject DN.  The signer certificate is not
available.  Ensure that the [wantAssertionsSigned] custom
property is set to true.

Also, if com.ibm.ws.security.web.* trace is enabled, the
following entry will be in the trace:

Unable to evaluate trusted Issuer Subject DN because the
[wantAssertionsSigned] property is set to false.


The fix for this APAR is currently targeted for inclusion in
fix packs 7.0.0.41, 8.0.0.12, and 8.5.5.8.  Please refer to
