Current File(s): conf/c14n/x500-subject-c14n-config.xml (V4.0), conf/c14n/subject-c14n.properties (V4.1+)
Format: Native Spring, Properties (V4.1+)
Overview
The c14n/x500 post-login subject canonicalization flow extracts a username from a Java Subject that contains either a single X509Certificate object in the public credentials set or a single X500Principal in the Principal set. It is primarily designed to work in conjunction with the X509 or X509Internal login flows.
General Configuration
Use conf/c14n/x500-subject-c14n-config.xml to configure this flow. |
Use conf/c14n/subject-c14n.properties to configure this flow. If your system is upgraded, you may continue to use conf/c14n/x500-subject-c14n-config.xml as before, or you may remove it, while ensuring the new properties are being loaded. The regular expression replacement feature is the only one remaining that still requires XML and you may define that bean, if needed, in conf/c14n/subject-c14n.xml |
|
By default, the subject DN is searched for a "CN" RDN attribute (with OID 2.5.4.3). You can configure alternative attributes to search for, or give preference to subjectAltName extensions (if an X509Certificate is present).
By default, the only transform applied to the result is a trim of leading or trailing whitespace. Case-folding and regular expression replacements can be added, per the reference section below.
