I've been setting up iRedMail for deployment later this month.   I had to move on to other projects so this server has been idle for about 2 weeks.  When I moved back to it today I found I was unable to authenticate with SOGo or iRedMailAdminPro.   Existing users do not work.   

I rebooted the server.   No change.

I attempted to bind to the LDAP server using an LDAP browser, it worked fine.   I used the vmailadmin user when binding.

I have no idea what happened over the past two weeks when the server was idle.   

Does authentication between iRedMailAdmin-Pro and the LDAP get logged?    When attempting to login the following appears in /var/log/messages:
May  2 13:28:53 stmail uwsgi: stmail.luzerne.edu [pid: 6337|app: 1|req: 7/8] 10.3.138.2 () {60 vars in 1795 bytes} [Thu May  2 13:28:53 2019] POST /iredadmin/login => generated 0 bytes in 15 msecs (HTTP/1.1 303) 3 headers in 230 bytes (2 switches on core 0)

The credentials I'm entering are correct.

When attempting to login using SOGo I received the following in /var/log/messages:
May  2 13:29:01 stmail systemd: Created slice User Slice of sogo.
May  2 13:29:01 stmail systemd: Started Session 192 of user sogo.
May  2 13:29:02 stmail systemd: Removed slice User Slice of sogo.

May  2 13:29:04 stmail php-fpm: [02-May-2019 13:29:04] NOTICE: [pool inet] child 25845 started

These errors don't seem to helpful.   Is there any middleware between LDAP and iRedAdminPro and/or SOGo?

Thanks,
Bob
