Currently Hudson only checks for attribute member in LDAP groups. However, it is
also quite common to use attribtute uniqueMember to store member list.

In WEB-INF/security/LDAPBindSecurityRealm.groovy, an one-line change that makes
Hudson search for both member=

can be done as follows:

authoritiesPopulator(DeferredCreationLdapAuthoritiesPopulator,initialDirContextFactory,"ou=groups")
{
// groupRoleAttribute = "ou";
groupSearchFilter = "(|(member=

))"
}

Thanks to Kohsuke.Kawaguchi@sun.com for the above code.
