ldap Deprecated conditional expansion

Hi All, I keep seeing this in the logs: [ldap] WARNING: Deprecated conditional expansion ":-". See "man unlang" for details I assume it's from this filter: [ldap] expand: (&(uid=%{Stripped-User-Name:-%{User-Name}})(!(inetCOS=802.1x_disabled))) -> (&(uid=hh52)(!(inetCOS=802.1x_disabled))) but I'm not sure what uid=%{Stripped-User-Name:-%{User-Name} should be set to instead. Any ideas? Cheers, Harry
