The only authenticated binds to our directory service that we support are GSSAPI binds. On Linux, Cyrus SASL/malloc leak memory bad enough that without either hoard or tcmalloc OpenLDAP is unusable.
This has nothing to do specifically with Cyrus SASL/GSSAPI, and everything to do with how glibc mallocs memory. I can make any linux system fairly unusable running OpenLDAP with a good sized database and a lot of read activity. Including Stanford's database. ;)
