pam and ldap authentication same time ?

[JOYDEEP]

Dear list,

To use LDAP  authentication (which is working already) I have set the
/etc/sysconfig/saslauthd   with    SASLAUTHD_AUTHMECH=ldap

no problem.  but I can not login to cyrus account to administer the
mailboxes.
because cyrus account use pam authenticatio. So is there any way to modify
/etc/sysconfig/saslauthd  to support both pam & LDAP ?

thanks
