[Dovecot] Dovecot director doveadm with switch "-A" error

[Ramon Frontera]

Hi,

we have installed dovecot version 2.1.11


Now we have found 3 problems with doveadm on proxy server:

1 problem:
In our configuration we have:
protocol doveadm {
auth_socket_path = director-userdb
}
 
I have executed this:
# doveconf -m doveadm -f service=doveadm auth_socket_path
auth_socket_path = director-userdb

Now when We execute doveadm quota get -A
we have this error: 
doveadm(user1): Error: /var/run/dovecot//auth-userdb: Proxy is missing destination host (maybe set auth_socket_path=director-userdb)
doveadm: Error: Failed to iterate through some users

with "-o auth_socket_path=director-userdb " it works for the early users.


2 problem
when we execute doveadm -o auth_socket_path=director-userdb quota get -A it works for the early users and then return this error on proxy:

doveadm(userabc): Fatal: table formatter doesn't support multi-line values


3 problem
I have tested other doveadm command on proxy wich also fails:

# doveadm -o auth_socket_path=director-userdb  search -u user  mailbox Trash savedbefore 1d

on proxy we have this error: " doveadm(user): Error: xx.xx.xx.xx:24245: Internal failure for user"
on mailserver we have this error: "doveadm: Fatal: master: service(doveadm): child 22171 killed with signal 11 (core dumps disabled)"

I put the gdm bt output hope it help you. (mailserver)
