DNS lookup issues? MIT's Kerberos replay cache? If it is pausing in the
GSSAPI negotiation, see if you can figure out which function call is
hanging the longest using a one entry result and -d -1 to ldapsearch.

It turns out, that this is only a problem when selinux is enabled. Turn
off selinux and SASL is much faster. I do not know if saslauthd or
Kerberos is the problem. I have been able to recreate the issue with
the sasl-sample client and server when selinux is enabled. I have also
been able to recreate the issue with the CentOS 6.3 build of Cyrus SASL
2.1.23 and my own build of Cyrus SASL 2.1.25 on CentOS 6.3. On my todo
list is to re-post the issue to the SASL mail list, but unfortunately I
have not had time.

is hanging. When I get a chance, I will try gprof on saslauthd.
