Though I could not reproduce the situation, I found a strange point
in your log which records "*" as IDENTified user name in spite of
the successful result "root" from the IDENT server.
This is caused because I spelled strncmp() for strcmp() in xferlog.c.
This bug could cause the problem you encountered ...

You cannot limit users of FTP-DeleGate based on "username+password"
authentication.  Only limitation based on client's host name/address
and/or client's usename by Ident server is applicable.
