没有来自远程身份验证服务器的[警报]意外响应

Question

当我在一段时间内运行测试时所看到的

socket(PF_LOCAL, SOCK_STREAM, 0)        = 3
connect(3, {sa_family=AF_LOCAL, sun_path="/var/run/saslauthd/mux"}, 110) = 0
writev(3, [{"\0\34a.chaouche@domain.tld\0\fxxx\0\4imap\0\0", 52}], 1) = 52
read(3, "\0@", 2)                       = 2
read(3, "NO [ALERT] Unexpected response from remote authentication server", 64) = 64
close(3)                                = 0
write(1, "0: NO \"authentication failed\"\n", 300: NO "authentication failed"
) = 30
exit_group(-1)                          = ?
+++ exited with 255 +++
root@messagerie[10.10.10.20] ~ # 

在命令行中，我看到的唯一一件事是：

root@messagerie[10.10.10.20] ~ # testsaslauthd -u a.chaouche@xxx -p xxx -f /var/run/saslauthd/mux -s smtp
0: NO "authentication failed"
root@messagerie[10.10.10.20] ~ # 

添加这个领域没有改变任何事情

root@messagerie[10.10.10.20] ~ # testsaslauthd -u a.chaouche@domain.tld -p xxx -f /var/run/saslauthd/mux -r domain.tld -s smtp
0: NO "authentication failed"
root@messagerie[10.10.10.20] ~ # 

saslauthd是从-a rimap -O localhost开始的，连接到信使自己的authdameon。

root@messagerie[10.10.10.20] ~ # saslauthd -a rimap -O localhost -c -m /var/run/saslauthd/
root@messagerie[10.10.10.20] ~ # pgrep -a saslauthd
1749 saslauthd -a rimap -O localhost -c -m /var/run/saslauthd/
1750 saslauthd -a rimap -O localhost -c -m /var/run/saslauthd/
1751 saslauthd -a rimap -O localhost -c -m /var/run/saslauthd/
1752 saslauthd -a rimap -O localhost -c -m /var/run/saslauthd/
1753 saslauthd -a rimap -O localhost -c -m /var/run/saslauthd/
root@messagerie[10.10.10.20] ~ # 

在syslog中，我可以看到imap身份验证已经收到并已经成功。

Mar 28 14:42:57 messagerie authdaemond: received auth request, service=imap, authtype=login
Mar 28 14:42:57 messagerie authdaemond: authmysql: trying this module
Mar 28 14:42:57 messagerie authdaemond: SQL query: SELECT email, password, "", 113, 120, "/var/vmail/", maildir, quota, 0, "" FROM users WHERE email = 'a.chaouche@domain.tld'
Mar 28 14:42:57 messagerie authdaemond: password matches successfully

Mar 28 14:42:57 messagerie imapd: LOGIN, user=a.chaouche@domain.tld, ip=[::1], port=[58425], protocol=IMAP
Mar 28 14:42:58 messagerie imapd: LOGOUT, user=a.chaouche@domain.tld, ip=[::1], headers=0, body=0, rcvd=19, sent=250, time=1

我确保了mux文件的存在并且位于正确的位置。这也是在777年的模式(没有改变)

root@messagerie[10.10.10.20] ~ # ls /var/run/saslauthd/
total 968K
-rw------- 1 root root    0 Mar 28 14:38 cache.flock
-rw------- 1 root root 963K Mar 28 14:38 cache.mmap
srwxrwxrwx 1 root root    0 Mar 28 14:38 mux
-rw------- 1 root root    0 Mar 28 14:38 mux.accept
-rw------- 1 root root    5 Mar 28 14:38 saslauthd.pid
root@messagerie[10.10.10.20] ~ # 

任何帮助配置塞勒斯的优点，以使用信使的imap服务器进行身份验证。

Courier随libfam0而来，但是对于某些原因，安装gamin重新解决了这个问题(并卸载了libfam0)。
