Every once in a while with SSSD, we run into a problem where we aren't able to 
get user information or authenticate users.  We are using ldap/kerberos against 
an Active Directory set up over SSL (LDAPS) and we see the following message in 
the logs:

encoded packet size too big (813957100 > 16777215)

From what I've been able to gather, this is something to do with the cyrus-sasl 
package.  I've also seen this error pop up when doing operations with the 
openldap-clients (ldapsearch, ldapmodify).  I've found that by specifying the 
minssf and maxssf values in the ldap* operations that the operations would then 
succeed.

I'm wondering if the same type of fix would work for SSSD?  Is there a way to 
specify the SSF of the SASL operations that SSSD uses?  Is there another 
workaround for this?
