I wrote about that to security () apache org in January. No response either.
Would be surprised if not a whole lot of other people noticed it as well.
A 2.0.x version I checked back then had the same problem iirc.
Thought they'd fix it at some point.

This is valid for the htpasswd utility of at least apache 1.3.27 and 1.3.28:
The salt used for password generation solely depends on the current
(void) srand((int) time((time_t *) NULL));
ap_to64(&salt, rand(), 8);
This causes all passwords generated within the same second to have the
same salt value. This in turn may cause auto-generated default passwords
to have the same value which could be a point of attack if the password
file is not properly protected.
The apache team was notified on 23.08.2003 but didn't respond.
Though it would need quite some administrative errors before the above
could be used it should still be corrected.
