cyrus sieve authentication

Hello,

I run an instance of mail/cyrus-imapd32 for a small number of users
with saslauthd authentication.

However, sieve authentication doesn't work.

Cyrus-imapd was compiled as below:

# make showconfig
===> The following configuration options are available for cyrus-imapd32-3.2.9_1:
     AUTOCREATE=on: Enable autocreate support
     BACKUP=off: Enable backup support (experimental)
     CLAMAV=off: Use ClamAV
     DOCS=on: Build and/or install documentation
     HTTP=off: Enable HTTP support
     IDLED=on: Enable IMAP idled support
     LDAP=off: Enable LDAP support (experimental)

     GSSAPI_HEIMDAL=off: GSSAPI support via security/heimdal
     GSSAPI_MIT=off: GSSAPI support via security/krb5
     GSSAPI_BASE=on: GSSAPI support via base system (needs Kerberos)
====> Command line editing via libreadline: you can only select none or one of them
     READLINE_GNU=off: Use Term::Readline::GNU for cyradm
     READLINE_PERL=off: Use Term::Readline::Perl for cyradm
===> Use 'make config' to modify these settings

When I try to connect:

# telnet localhost sieve
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
"IMPLEMENTATION" "Cyrus timsieved 3.2.7"

"NOTIFY" "mailto"
"EXTLISTS" "urn:ietf:params:sieve:addrbook"
"STARTTLS"
"UNAUTHENTICATE"
OK

The example on the Cyrus web site shows:

[...]

"IMPLEMENTATION" "Cyrus timsieved v1.1.0"
"SASL" "ANONYMOUS PLAIN KERBEROS_V4 GSSAPI"
"SIEVE" "fileinto reject envelope vacation imapflags notify subaddress regex"
OK

Someone on the Cyrus mailing list suggested that KERBEROS_V4 and GSSAPI
are required for sieve authentication.

Is that correct? If so, what compile options should I choose?

Please advise.
