I noticed that in Active Directory Settings there is some checkbox like "Verbose Logging", but i can't see it in LDAP settings... maybe this is that error?

Hmm... I just using for tests this:
github.com

docker-openldap/example/docker-compose.yml at master · osixia/docker-openldap

OpenLDAP container image . Contribute to osixia/docker-openldap development by creating an account on GitHub.
github.com github.com

Btw. I am trying to configure LDAP to make LDAP authentication for True NAS Samba.

I'm trying to do it following this guide:

JumpCloud Support Community

support.jumpcloud.com support.jumpcloud.com

So far looks like everything working. Just stuck on last step with this START_TLS config.

It's very weird situation because when i click on "Save", on LDAP logs i can see established connection but when i type from NAS "pdbedit -L" then in logs i can see that can't connect....

NAS:

LDAP:

Btw you mean that i should disable TLS in Docker LDAP configuration?

just to clarify:
Code:
root@truenas[/var/log]# cat /etc/hosts

# $FreeBSD$
#
# Host Database
#
# This file should contain the addresses and aliases for local hosts that
# share this file.  Replace 'my.domain' below with the domainname of your
# machine.
#
# In the presence of the domain name service or NIS, this file may
# not be consulted at all; see /etc/nsswitch.conf for the resolution order.
#
#
::1                     localhost localhost.my.domain
127.0.0.1               localhost localhost.my.domain
#
# Imaginary network.
#10.0.0.2               myname.my.domain myname
#10.0.0.3               myfriend.my.domain myfriend
#
# According to RFC 1918, you can use the following IP networks for
# private nets which will never be connected to the Internet:
#
#       10.0.0.0        -   10.255.255.255
#       172.16.0.0      -   172.31.255.255
#       192.168.0.0     -   192.168.255.255
#
# In case you want to be able to connect to the Internet, you need
# real official assigned numbers.  Do not try to invent your own network
# numbers but instead get one from your network provider (if any) or
# from your regional registry (ARIN, APNIC, LACNIC, RIPE NCC, or AfriNIC.)
#

127.0.0.1       truenas.local truenas
::1             truenas.local truenas
192.168.0.15    ldap-server


so:
ldap-server (docker container) is in 192.168.0.15
true nas is in 192.168.0.12

ping from nas:
Code:
root@truenas[/var/log]# ping ldap-server
PING ldap-server (192.168.0.15): 56 data bytes
64 bytes from 192.168.0.15: icmp_seq=0 ttl=64 time=0.460 ms
64 bytes from 192.168.0.15: icmp_seq=1 ttl=64 time=0.297 ms
64 bytes from 192.168.0.15: icmp_seq=2 ttl=64 time=0.442 ms

If you're trying to use SMB with LDAP, I highly recommend using samba AD rather than trying to get the legacy LDAP passdb backend working (see notes in GUI about SMB/LDAP deprecation).

Otherwise, if for some reason, you _must_ use this docker app, you can delete the log message for SASL_EXTERNAL from /usr/local/lib/python3.8/site-packages/middlewared/plugins/ldap.py.

IIRC, pdbldap doesn't support SASL_EXTERNAL and so you most likely won't be able to use SMB with that docker app.

Structure of my LDAP:

1621425311335.png


when i configure in True NAS to use LDAP without encryption "Off" then:

1621425402016.png


But when i try to map directory:
1621425746930.png



I highly recommend using samba AD
Click to expand...
samba AD? it is not a Windows AD? it is open source like openLDAP?

a big advantage using LDAP is that i would have just one user's database for Samba and for example Nextcloud and other services authentication.
