authentication failure (wrong key)

[thbtcllt]

Since commit ae6e90a authentication is no more possible.

The issue is due to the following change

•        for(i = tac_srv_no-1; i >= 0; i--) {
  

•        for(i = tac_srv_no-1; i != 0; i--) {
  

in the support.c file
With this change the key is no more store for the first server (the case of i equal 0)

So a configuration like
auth required /lib/security/pam_tacplus.so debug server=1.1.1.1 secret=SECRET-1
does not work anymore (the secret SECRET-1 is no more set for the server 1.1.1.1)
