AIX authenticate()

[Jan-Frode Myklebust]

Hi, 

I just got a comment from one of my IBM support engineeres that there
is a problem with auth-passwd.c only calling authenticate() once. He
claims it should potentially be called several times, in case several
authetication methods are defined in /etc/security/user. F.ex.:

	SYSTEM = "NIS and DCE"

Suggested (untested) patch should look like:

----------------- cut --------------------

It kind of looks like it's a slip that this isn't fixed in
auth-passwd.c, as 'int reenter = 1;' is already available inside
WITH_AIXAUTHENTICATE.
