according to rfc2307 which says the memberUid is a name (not a uid
strangely enough)

ldap_schema description and my broken install on ubuntu...

I can't say what ldif I used except it was standard (I didn't write it)
and ldapscripts and phpmyadmin all seem to want the field to be a name.

Possible fix for JENKINS-9806, fix empty customWorkspace -if empry, replace it by null (i.e. no custom workspace)

properties.

[FIXED JENKINS-9807] : [Maven Jobs] Post build deploy task : Deploy with unique versions (timestamp) should be configured by default

Dependency

Replace crappy VersionNumber with better implementation.

replace old CDDL+GPLv2 Version Number comparator with one that is both ASL and has a better understanding of Maven version numbers (with some tweaks for wildcard support)

o Had to change the logic of two test cases (2.0 is now newer than 2.0.ea and 1.12-SNAPSHOT is no longer equal to 1.11.*) both of which make more sense than the original test cases

o Should now allow custom builds with text/alpha qualifiers in the version number.

the root name of a system property. Obviously changing the root class
name breaks this. So introduce a simple Configuration class that is
used to first try Jenkins variables, then back off to Hudson variables
if not found.
