pam module (pam_exec)

[Anthony BERGER <anthony.berger@cea.fr>]

hi,

I wonder why the pam module pam_exec is not present in the package 
pam-modules (etch).

I would need this to test if a central authentication server (openldap) 
is present or not in order to bypass the ldap authentication in case of 
it is unavailable : the failover is very very long if the network is 
unreachable. (pam_ldap.so)


Maybe i need to write a pam module to test accesibility of the ldap 
server!!?
(for exemple : pam_isreachable.so nbtry=3 typetest=ping servertype=pam 
=> it would read the pam_ldap.conf and test the ping on all server)

is exist another solution?

thank you very much for your help.
