Hi guys.
I am getting strange error:
BUG: Unknown command in userdb socket: CPID?2625
I am using service auth to authenticate users on postfix.
My OS:
# cat /etc/os-release
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"
CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="
My dovecot:
# dovecot --version
2.2.10
My config:
service auth {
unix_listener auth-userdb {
mode = 0600
user = postfix
group = postfix
}
}
My Postfix:
# rpm -qa | grep postf
postfix-2.10.1-6.el7.x86_64
Log:

The interesting thing is IF I am taking off "-" (minus) from the
socket name, everything works just perfect! So if I change config
to:
service auth {
unix_listener blabla {
mode = 0600
user = postfix
group = postfix
}
}

P.s. I don't mind to use socket without minus on its name. But
this looks really strange. Thanks. You are awesome
