We do SASL GSSAPI authentication against IPA LDAP server. The reason for
that is because cifs/... principal has special rights in LDAP to read
and write keys of TDO objects and ability to set up access to them for
SSSD on IPA master.

Thus, BIND callback is really important to have to FreeIPA.

Would a similar 

 void smbldap_set_bind_callback(struct smbldap_state*, bindproc, void  *binddata);

where bindproc is what we have already

int (*bind_callback)(LDAP *ldap_struct, struct smbldap_state *ldap_state, void *data);

be acceptable?
