Hello

We're using this pam_cas module (tested on CentOS 7 & 8) :
https://github.com/EsupPortail/esup-pam-cas

On cyrus frontend, cyrus-sasl is running with MECH="pam"

/etc/pam.d/imap :
#%PAM-1.0
auth       sufficient   pam_cas.so -simap://<CYRUS-FRONTEND> -f/etc/pam_cas.conf
auth       sufficient   pam_ldap.so
account    sufficient   pam_ldap.so
auth       required     pam_nologin.so
auth       include      password-auth
account    include      password-auth
session    include      password-auth

With that, it's OK for Wevmail+CAS and Thunderbird/Outlook (authenticated against LDAP)

Hope it's help you.

My users access the server either with thunderbird or with SOGo (https://www.sogo.nu).

I configured cyrus to authenticate with saslauthd in ldap mode, i.e:

sasl_pwcheck_method: auxprop saslauthd
sasl_auxprop_plugin: sasldb
sasl_minimum_layer: 0
sasl_mech_list: anonymous login plain  sasldb

(auxprop is for the cyrus user which is not in ldap).

With SOGo I'm currently using basic auth, so SOGo can use the same credentials to login into cyrus and sieve, but I'm testing an SSO solution based on lemonldap.

Lemonldap can fake basic auth and that works, but I'd like to use either saml or cas.

There's a pam module for cas (https://github.com/atiti/pam_cas-reloaded) and a pam/sasl module for saml (crudesaml https://github.com/univention/crudesaml), but I only see documentation on how to use them with dovecot.

Has anybody used either one with cyrus instead? How?

TIA

Bye
