cyrus imap badlogin response delay

[LALOT Dominique]

Hello,

When there is a bad login, the answer is very long. I want to get if 
faster even if it's worst for security purpose. I've tried to find an 
answer about that question, buit nothing evident.
I'm using cyrus imap 2.2.12.

sasl_pwcheck_method: saslauthd
sasl_mech_list: PLAIN
allowplaintext: yes

usr/sbin/saslauthd -m /var/run/saslauthd -a pam -c -t 3600 -s 3000 -n 15

/etc/pam.d/imap
auth sufficient /lib/security/pam_cas.so 
-simap://smtp-etumel.univ-mrs.fr -f/etc/pam_cas.conf
auth        sufficient    pam_ldap.so
auth        required   pam_unix.so nullok nodelay
account    sufficient pam_ldap.so
account     required   pam_unix.so nodelay

time testsaslauthd -u fred -p pipo
0: NO "authentication failed"
real    0m0.056s
user    0m0.000s
sys     0m0.000s


It's quich enough. But under cyradm -> 5 secondes

I saw nothing valuable  in imapd.conf. What can I do?

Thanks

Dom
