As of 10.1 M030, default Windchill behavior has changed to display only Full name and Last as-is from LDAP, without parsing. This is because parsed names have not been meeting customer expectations. This change is documented in the What’s New guide for that release.
It is possible for the customer to go back to displaying First, Middle, etc. (as described in the guide above) – but again, these values will be derived by parsing and not mappings. So if making a switch, the customer must be made aware of the known limitations of using parsing. Also, as of 10.2, these name parts (First, Middle, Prefix, Suffix) will no longer be supported and only Full Name and Last will be. So the default behavior is what we recommend they go with.
