I am trying to setup SOGo Groupware as you describe in tutorial at http://www.iredmail.org/docs/sogo-cento … ldap.html.
For vacation message I need to setup master user and after setup it I have errors in dovecot.log:
  auth: Fatal: ldap: LDAP attribute 'mail' used multiple times. This is currently unsupported.
  master: Error: service(auth): command startup failed, throttling
Setup related to master user:
dovecot-ldap.conf
  user_attrs  = mail=master_user,mail=user,homeDirectory=home...
dovecot.conf
  # Master user
  auth_master_user_separator = *
  passdb {
    driver = passwd-file
    master = yes
    args = /etc/dovecot/dovecot-master-users
  }
I also setup file dovecot-master-users.
Does my dovecot version need update to support this or the problem is somewhere in configuration?
My server is updated from earlier version to 0.9.5_1 related to tutorial you provide to us!
Any help?
Many thanks!
