Hello Zhang,
I don't know why but I replace:
- main.cf
- master.cf
- virtual_group_maps.cf
- virtual_group-members_maps.cf
- dovecot.conf
- dovecot-ldap.conf
By file extrated from a fresh VM installed with same parameter.
And everything is now OK...
No log with multiple values, alias and groups are working fine.
Perhaps update 0.9.5 to 0.9.9 the script had a problem... (it is since I've make this update the issue was)
Thanks again for all.
Regards
We can close this issue
