Hello List ,

I am sorry if this query doesn’t belong here , but I am trying to configure Cyrus SASL on Postfix to use our LDAP servers for authentication ,

The moment I turn on SASL auth on main.cf , telnet to the system on port 25 starts to fail , I see the below errors in maillog :

Apr 24 11:07:09 XXXXXXXX postfix/smtpd[19352]: xsasl_cyrus_server_create: SASL service=smtp, realm=(null)

Apr 24 11:07:09 xxxxxxxxxx postfix/smtpd[19352]: name_mask: noanonymous

Apr 24 11:07:09 xxxxxxxxxx postfix/smtpd[19352]: name_mask: noplaintext

Apr 24 11:07:09 xxxxxxxxxx postfix/smtpd[19352]: warning: xsasl_cyrus_server_get_mechanism_list: no applicable SASL mechanisms

Apr 24 11:07:09 xxxxxxxxxx postfix/smtpd[19352]: fatal: no SASL authentication mechanisms

My smtpd.conf file :

pwcheck_method: auxprop

auxprop_plugin: ldapdb

mech_list: PLAIN LOGIN

ldapdb_uri: ldaps://xxxxxxxxxxx:636

ldapdb_id: uid=xxxxx,ou=people,ou=xxx,o=World

ldapdb_pw: xxxxxxxxxx

#ldapdb_mech: DIGEST-MD5

Just wondering if someone can share their input on this .

Best regards,
