[Web-cyradm] change password

[Oberdan Albertoni]

Hello,
I have web-cyradm on debian and are all ok.
I use pam_mysql to authenticate user, but when I change password for a 
user in the mysql table the password is changed but if I try to connect 
with the old password cyrus-imap permit me  to login.
It seems that salsauthd keep in chache the password.

I tray to connect with :

1) testsaslauthd -u USER1 -p PASSWORD1   is OK
2) with web-cyradm change passowrd for USER1 to  PASSWORDNEW
   ( in the db there is the new password )
3) testsaslauthd -u USER1 -p PASSWORD1   and it's stil OK
4) testsaslauthd -u USER1 -p PASSWORDNEW  is OK
5) testsaslauthd -u USER1 -p PASSWORD1  now recivied 0: NO 
"authentication failed"

How can tell to  salsauthd to view the new password in the DB ?

Thank You.
Obe.
