Re: SMTP Error (535): Authentication failed.

It says "no fields returned by the server". that means no such user. Do you have any account matches below LDAP query filter?

Re: SMTP Error (535): Authentication failed.

Thanks, i managed to find the cause after i run  ldap search on the real email account

ldapsearch -x -D 'cn=Manager,dc=domain,dc=com' -W "(mail=user@domain.com)

and then compared the result to ldap query filter,  i found that  the real email account was missing an attribute "enabledService=smtpsecured"

i  run update updateLDAPValues_061_to_070.py  and that sorted the problem.
