Have you, perhaps, got a lot of logins (possibly even 19 of them) which are
"locked out" because the system admin has put "NO PASSWORD" (or something
else similarly negative :-) ) in the password field?  


I get 

   1 *n		     1 FB	       1 Zf		 1 vC
   1 /2		     1 Gs	       1 c0		 1 vV
   1 /p		     1 H.	       1 c8		 1 w/
   1 /z		     1 Hj	       1 cS		 1 wX
   1 0A		     1 IH	       1 f5		 1 xA
   1 0z		     1 Ke	       1 jG		 1 xR
   1 5Q		     1 Kq	       1 jm		 1 xk
   1 6J		     1 Kw	       1 nN		 1 zP
   1 7H		     1 Rh	       1 oR		 4 NP
   1 8Z		     1 SA	       1 qg		 6 *L
   1 90		     1 SL	       1 th		29 np
   1 Cc		     1 Tl	       1 u1



and guess what - there are 29 locked logins, flagged by having a password
field of "np" (looks like one *np* in there, as well).
