This bit is unnecessary, the PRIVSEP macro is for this purpose, ie:

    debug("=== calling log_btmp uid %d ===\n", getuid());

Sending the username is unecessary as the monitor already knows it (ie
authctxt->user).  Hostname can be determined too (see mm_record_login).  As a
general rule, as little as possible should be sent from slave to monitor.

It's out of the scope of this bug but I'd prefer to see a generalized
audit_event like in bug #125 in both OpenBSD and Portable, which could be
easily extended to handle cases like this.
