Hi everybody,
I am completely new to this group - and to OpenLDAP as well. Trying to get rid of our
Windows SBS domain controller I am building a new Samba 4 server dedicated only to domain
controlling, Debian 10.4, Samba 4.9.5. I'm doing this from scratch, following the
textbooks. I've also setup LAM as graphical interface for administration.
But once I try logging into the server's profile via that LAM interface as
Administrator, I get this: "LDAP error, server says: (8) Strong(er) authentication
required".
(1) "ldbsearch -H ldap://ldap.[my].[domain] "cn=Administrator" -k
yes": is working with the same password I would use in LAM
(2) Server profile settings in LAM
- TLS is deactivated
- Login: Fixed list, cn=Administrator,cn=users,dc=[my],dc=[domain]
(3) ldap.conf
#
# LDAP Defaults
#
# See ldap.conf(5) for details
# This file should be world readable but not world writable.
BASE dc=[my],dc=[domain]
URI ldap://ldap.[my].[domain] ldap://ldap-master.[my].[domain]:666
#SIZELIMIT 12
#TIMELIMIT 15
#DEREF never
# TLS certificates (needed for GnuTLS)
#TLS_CACERT /etc/ssl/certs/ca-certificates.crt
What am I doing wrong?
Help appreciated, thank you!

I've no idea what ldbsearch does behind the scenes, I do not see a "-k"
option documented for it, so no clue what that does.

Well any limitation on authentication would be in the server config, not
ldap.conf. My guess is there's a security requirement that ldb is meeting
when it does the connection that LAM is not.

Thank you, but I was given the solution in another group:
"Did you configure LDAPS in LAM? The message comes from Samba and not
from LAM. It has something to do with the bedlock Bug read this:
https://www.kania-online.de/ldb-tools-nach-badlock/
I wrote how you can disable the secure settings."
