I tried with plain: /opt/mail/cyrus-imapd/bin/imtest -m plain -p imap
And it got rejected.

I can not find a tls conf file so I do not thing starttls is set up.
I added the entry mentioned to imapd.conf
$ cat /etc/imapd.conf

proxy_password: password

And it gets things furthur along then before

If I can take a step back (sorry I'm trying to decipher how the previous
admin had things set up in the environment). The document on how this was
set up states.
cyrus-sasl was config'ed with
./configure --prefix=/opt/mail/cyrus-sasl \
--enable-login --enable-plain --enable-cram \
--enable-digest --with-bdb-incdir=/usr/include/db4 \
--with-pam --enable-static=yes --enable-sample \
--disable-java --disable-otp --disable-krb4 \
--with-plugindir=/opt/mail/cyrus-sasl/lib/sasl2
The cyrus-sasl cyrus.conf states:
srvtab: /var/imap/srvtab <<< seems I could remove this since kerberos is
disabled above.
pwcheck_method: saslauthd
saslauthd is started in with pam support:
root 2060 0.0 0.0 2564 1036 ? S Apr14 0:00
/usr/sbin/saslauthd -m /var/run/saslauthd -a pam
There is /etc/pam.d/imap and pop3 with the following content..
#%PAM-1.0
auth required /lib/security/pam_stack.so service=system-auth
account required /lib/security/pam_stack.so service=system-auth
Cyrus-imap was compiled with (again what is in the notes from install from
previoys admin)
CFLAGS=-I/usr/kerberos/include ./configure --prefix=/opt/mail/cyrus-imapd
\
--with-cyrus-prefix=/opt/mail/cyrus-imapd \
--with-cyrus-user=cyrimap \
--with-cyrus-group=mail \
--with-bdb-incdir=/usr/include/db4 \
--build=i686-pc-linux-gnu \
--with-sasl=/opt/mail/cyrus-sasl \
--with-auth=unix \
--enable-netscapehack \
--enable-listext \
--with-perl=/opt/third-party/bin/perl \
--disable-murder
I can run a testsaslauthd and it works fine to the local host
server1.sub1% /usr/sbin/testsaslauthd -u cyrus -p password -R 3
0: OK "Success."
1: OK "Success."
2: OK "Success."
It seems I do not need to have a realm defined because we are using pam.
and if I do a sasldbpasswd2 it says /etc/sasldb2 does not exist. This not
seem to be the problem though since saslauthd is using pam. yes?
When I login into cyradm again locally with --auth plain I can do commands
like listmailbox and such. I can't seem to be able to run "info" I just go
back to the prompt on that one.
What should my security flags be? What am I missing?
Thank you
perry
You need to use tls as well for PLAIN to work. add -t "" to your
arguments
What mechanism do you want to use for connecting between backends? If its
PLAIN then you want
force_sasl_client_mech: PLAIN
in your imapd.conf file.
Otherwise, the machines will see GSSAPI advertised and will try using
that.

Thanks for the imtest idea.
It looks like I can log in OK.
server1.sub1% /opt/mail/cyrus-imapd/bin/imtest -m login -p imap
server2.sub2.domain.com
Force imtest to use one of the SASL mechanisms that are listed. The
backends *only* use SASL, not protocol specific login commands (IMAP
LOGIN, POP3 USER/PASS, NNTP AUTHINFO USER/PASS).
I'm sorry I got my dounce cap on today or something.
Should I change the -m login to -m and one of the AUTH= values from the
CAPABILITY output?
ie -m GSSAPI? or digest-md5 etc...

Maybe "-m plain"?
thank you for the suggestion Andy but no luck.

This is in the auth.log

cram-md5 got me pretty much the same thing.
Is there a cyrus or sasl command I should/can run to get the auth for
digest-md5 working?
