FreeIPA 및 Roundcube를 사용하여 Docker에서 메일 서버 설정

자체 메일 서버를 설정하고 Ldap(FreeIPA)을 통해 인증을 시도했습니다. 이 모든 작업은 Docker 컨테이너 내에서 실행되어야 합니다. 내가 뭘 잘못했는지 모르겠습니다. 어쩌면 내 LDAP 구성 일 수도 있습니다.

사용자를 생성하고 비밀번호 설정을 위해 처음으로 IPA에 로그인했습니다. Roundcube에 로그인하려고 하면 로그인 실패가 발생합니다. 메일 서버는 다음 메시지를 인쇄했습니다.

Dovecot DOVECOT_USER_FILTER, DOVECOT_PASS_ATTRS 및 DOVECOT_USER_ATTRS에 대한 올바른 LDAP 구문은 무엇입니까?
