PM76997: VMM CERTIFICATE AUTHENTICATION FAILS WHEN DN CONTAINS NON-DEFAULT X509CERTIFICATE ATTRIBUTES.

Fixes are available

APAR status

Closed as program error.

Error description

Certificate authentication fails with VMM when the subject
or issuer DN of the certificate contains attributes other than
the default X509Certificate attributes (CN, L, ST, O, OU, C,
STREET, DC, UID).

For example when certificate DN contains an attribute say
EMAILADDRESS like DN="CN=Bob Smith,OU=companyunit,O=company,
EMAILADDRESS=bob@company.com"
authentication fails with the following exception:

com.ibm.websphere.wim.exception.CertificateMapperException:
CWWIM0003E
The 'EMAILADDRESS' Distinguished Name field is unknown.

*                      Virtual Member Manager when             *
*                      Distinguished Name (DN) contains        *

****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
During certificate authentication, if the
subjectDN of issuerDN field retrieved from
the certificate contains non-default X509Certificate
attributes (such as CN, L, ST, O, OU, C, STREET, DC, UID), then
the non-default attributes are returned in their
Object Identifier (OID) form, due to which login fails with
invalid DN field error. This is applicable for both LDAP and
File repositories.
For example, if the certificate filter is:
certsubjectName=${SubjectDN}, and DN=CN=Bob
Smith,OU=companyunit,O=company,EMAILADDRESS=bob@company.com,
login fails with "CWWIM0003E The 'EMAILADDRESS' Distinguished
Name field is unknown" error message.

Problem conclusion

Instead of using cert.getIssuerX500Principal().getName() which
returns the non-default attributes in its OID form, the code
will now use cert.getIssuerX500Principal().toString() and
handle the spaces between the attributes appropriately.
