auxprop 不支持md5crypt類型的加密?

auxprop 不支持md5crypt類型的加密?

我安裝的版本是
cyrus-sasl-2.1.23
postfix-2.6.5,1
postfixadmin-2.3_1

用戶是通過 postfixadmin 添加到 pgsql 資料庫中的,密碼保存為類似 $1$86fa88b8$0rSw07ELxbMZSudFtGlzx0 這樣的字元串。

問題表現為:
telnet 登陸到 25 埠,當資料庫中保存的密碼是加密時,認證失敗。不加密保存時,認證成功。

如何讓它支持密碼加密?

/usr/local/lib/sasl2/smtpd.conf 文件內容為:


pwcheck_method: auxprop
log_level: 3
mech_list: PLAIN LOGIN CRAM-MD5 DIGEST-MD5
auxprop_plugin: sql
sql_engine: pgsql
sql_hostnames: 192.168.1.2
sql_user: mail
sql_passwd: mail123
sql_database: pmail
sql_select: SELECT password FROM mailbox WHERE username = '%[email protected]%r' AND active = true


/usr/local/etc/postfix/main.cf 文件中的一部分:


smtpd_sasl_auth_enable = yes
smtpd_sasl_authenticated_header = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_sasl_authenticated permit_auth_destination reject
smtpd_client_restrictions = permit_sasl_authenticated
smtpd_sender_restrictions = permit_sasl_authenticated
smtpd_sasl_path = smtpd

Cyrus-SASL 2.1.x patches

Available patches:
checkpw.c

This patch makes cyrus-sasl to authenticate crypt(3) hashed passwords from various backends (auxprop plugins) - so you can authenticate crypt hashed passwords in your sql database (this is probably why are you reading this homepage).

Patch adds the following plugin configuration directive:

    * password_format:

Installation

    *
          o Download cyrus-sasl-2.1.x.tar.gz from ftp://ftp.ANDrew.cmu.edu/pub/cyrus-mail/ (Also downloadable locally, here)
          o Download checkpw.c patch from download page
          o Unpack distribution (tar zxf cyrus-sasl-2.1.x.tar.gz)
          o Enter source directory (cd cyrus-sasl-2.1.x)
          o Apply patch (patch -p0 < ../cyrus-sasl-2.1.x-checkpw.c.patch)
          o Run configure (./configure)
          o Compile it (make)
          o Install it (make install)
    * FreeBSD ports collection
          o Download FreeBSD version of checkpw.c patch from download page
          o Put patch files in directory /usr/ports/security/cyrus-sasl2/files

Configuration

Configuration directive can be set to the following values:

    * plaintext - passwords are stored in plaintext format - this is default
    * crypt - passwords are stored as modular crypt hashes (md5 or blowfish crypt)
    * crypt_trad - passwords are stored as des crypt hashes (2 character salt crypt)

If configuration directive password_format is not specified, then passwords are considered to be in a PLAINTEXT format.

Example mailserver configuration (file smtpd.conf):

pwcheck_method: auxprop
auxprop_plugin: sql
allowanonymouslogin: no
allowplaintext: yes
mech_list: PLAIN LOGIN
srp_mda: md5

srvtab: /dev/null
opiekeys: /dev/null

password_format: crypt

sql_user: username
sql_passwd: password
sql_hostnames: sql.example.org
sql_database: database_name
sql_select: SELECT password FROM mailbox WHERE username = '%u' AND realm = '%r'

Download

    * version 2.1.19
    * version 2.1.19, FreeBSD Ports edition

如果sasl要支持crypt加密,是要打補丁的.

在安裝 /usr/ports/security/cyrus-sasl2 時,我鉤選了  AUTHDAEMOND,而且 authtest 測試也是正常的。

# authtest -s login [email protected] inmmged
Authentication succeeded.

     Authenticated: [email protected]  (uid 80, gid 80)
    Home Directory: /usr/virtual
           Maildir: ddss.org/iheaing/
             Quota: 51200000
Encrypted Password: $1$86fa88b8$0rSwa7ELxbMZSudFtGlzx0
Cleartext Password: inmmged
           Options: wbnodsn=1


當 /usr/local/lib/sasl2/smtpd.conf 文件內容改為下面這樣也不行:

pwcheck_method: authdaemond
authdaemond_path: /var/run/authdaemond/socket
log_level: 3
mech_list: PLAIN LOGIN
auxprop_plugin: sql
sql_engine: pgsql
sql_hostnames: 192.168.1.2
sql_user: mail
sql_passwd: mailer
sql_database: pmail
sql_select: SELECT password FROM mailbox WHERE username = '%[email protected]%r' AND active = true

/var/log/maillog 文件提示:

postfix/smtpd: connect from unknown
postfix/smtpd: warning: SASL authentication failure: could not verify password
postfix/smtpd: warning: unknown: SASL login authentication failed: generic failure
postfix/smtpd: lost connection after AUTH from unknown
postfix/smtpd: disconnect from unknown

把 courier-authlib 的日誌打開 文件名為:authdeamonrc,具體位置,根據你安裝方式,自己查找以下,看看 DEBUG_LOGIN 的值是多少,改成 DEBUG_LOGIN=2 試試。

看看日誌裡面有沒有更詳細的日誌。

/usr/local/lib/sasl2/smtpd.conf
改成


pwcheck_method: authdaemond
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path: /your/install/authdaemon/socket

修改 authlib 的配置文件 authmysqlrc 文件按照這個格式寫,根據你的事件情況,實際配置吧

MYSQL_SERVER localhost
MYSQL_DATABASE postfix
MYSQL_USERNAME postfix
MYSQL_PASSWORD passwd
MYSQL_USER_TABLE mailbox
MYSQL_LOGIN_FIELD username
MYSQL_CRYPT_PWFIELD password
MYSQL_UID_FIELD '1000'
MYSQL_GID_FIELD '1000'
MYSQL_HOME_FIELD '/var/mailbox/'
MYSQL_MAILDIR_FIELD CONCAT('/var/mailbox/',maildir)
MYSQL_NAME_FIELD name
MYSQL_QUOTA_FIELD concat(quota,'S')
MYSQL_WHERE_CLAUSE active='1'

似乎是正解,但我的是 cyrus-sasl-2.1.23,
cyrus-sasl-2.1.19-checkpw.c.patch可以用嗎?

我在忙其它,試過的同志說一聲。

應該是沒問題的

多謝淺嘗孤獨同志!第六樓的回答為最佳答案,有意見的站出來。

這個補丁在 2.1.19 就有了,為什麼還不集成到 2.1.23 版本呢?
