Do you mean that if I use both of them I can't use only one ldap configuration (the one used by pam_ldap) ? Today it's exactly what I have, twice the ldap configuration
I thought it would be feasible to use pam_ldap for the ldap access and sssd only to cache the password.

you'd actually centralize the configuration in one config file
(sssd.conf) instead of a combination of sssd.conf + pam_ldap.conf.
