Document

Creates an X500Principal from a string representation of an X.500 distinguished name (ex: "CN=Duke, OU=JavaSoft, O=Sun Microsystems, C=US").

Usage

From source file:org.globus.gsi.util.CertificateUtil.java

/**
 * Converts Globus DN format "/O=C/OU=B/CN=A" into an X500Principal
 * representation, which accepts RFC 2253 or 1779 formatted DN's and also
 * attribute types as defined in RFC 2459 (e.g. "CN=A,OU=B,O=C"). This
 * method should allow the forward slash, "/", to occur in attribute values
 * (see GFD.125 section 3.2.2 -- RFC 2252 allows "/" in PrintableStrings).
 * @param globusID DN in Globus format// w  w w .  j  av  a2  s . c  o  m
 * @return the X500Principal representation of the given DN
