For much larger range, insert the following code

122   L%=2*3*5*7*11*13:dim Diff%(L%):C%=0:' L=30030
124   for I%=1 to L%-1
126     if gcd(I%,L%)=1 then inc C%:Diff%(C%)=I%
128   next I%:' c%=5760

and add the following code.

200   Base=((2^32-5)\L%)*L%:N=10^11
210   for K%=1 to C%:P=Base+Diff%(K%):if prmdiv(P)<>P then 260
220     Pm=P-1:P2=P^2:P2m=P2-1
230     for I%=1 to J%:A=modpow(T%(I%),Pm,P2)
240       if or{A=1,A=P2m} then print T%(I%);":";P
250     next I%
260   next K%
270   Base=Base+L%:if Base<N then 210

This program covers up to 10^11.

Wilfrid Keller and Jörg Richstein computed for;

100 < a < 1000,  104 < p < 1011
a < 100,    232 < p

(Wilfrid Keller, Jörg Richstein,
Solutions of the congruence  ap-1≡1 (mod pr),
Mathematics of Computation, 74(2005), 927-936.)

Richard Fischer computed up to 2.311E+12.
For some data, the range reached 1.2E+13.
Current status is uploaded at here (in German). (February 23, 2009).

Solution

Now the search range of this page is larger than Wilfrid Keller and Jörg Richstein's results.
This page covers the integer pair a and p which satisfies

ap-1- 1≡0  (mod p2), where

a : 2 ≤ a ≤ 999, non perfect power number
p : p ≤ 1.72 x 1012, prime

I searched up to 8.6 x 109
The search results larger than 8.6 x 109 are owe to Richard Fischer (June 18, 2008).
