SASL: encoded packet size too big

Hello!

Dovecot uses it's own SASL implementation, doesn't it?

Looks like cyrus-sasl encountered same problem earlier. https://lists.andrew.cmu.edu/pipermail/cyrus-sasl/2017-March/003001.html

I never have such an issue with ldapsearch. So, I assume there is a similar problem in Dovecot SASL implementation.
