LDAPs AD bind
-
Oh, you are probably running the command via the WebGUI Command Line option, in which case do this:
export LDAPTLS_REQCERT=allow; ldapsearch -v -H "ldaps://dc1.local:636" -b "dc=local" -s sub -D "username@local" -w "password" -
Thanks. I plugged the following into the WebGUI CLI and obtained the following:
export LDAPTLS_REQCERT=allow; ldapsearch -v -h DC1.local:636 -s base -x "namingContexts"
ldap_initialize( ldap://DC1.local:636 )
ldap_result: Can't contact LDAP server (-1)I also got the same result plugging the IP in place of the hostname.
On the domain controller, I filtered my security logs for 4625 and 4624 event IDs with no results.
Thanks.

I did see an event log on the DC with an event ID of 2085.
"Internal event: An LDAP over Secure Sockets Layer (SSL) connection could not be established with a client."
Under 'Additional Data'
"Error value
2148074289 The client and server cannot communicate, because they do not possess a common algorithm. Internal ID: c05088d -
@rb_it_pf The command isn't correct, you cannot use -h host -p 636, as simply selecting a different port won't make ldapsearch use SSL, I know, its silly, but you really need to use -H "ldaps://host:636".

The command worked and outputted the DN.
I tried the other command that connects to the LDAP server and it worked as well. In fact i was able to see outputs for users that belong to the DC LDAP group.I still can't seem to search on the containers or successfully bind using the GUI though.
Any thoughts?

Solved. I had to restart the PHP-FPM in order for the SSL Transport type to take affect. I remember hearing about this in a Netgate video on LDAP but didn't think much of it at the time. Restarting PHP-FPM fixed it. I really appreciate your help troubleshooting with the CLI.

Happy to help, and glad you figured it out!

I have similar issues, and in the end, Im not sure what the resolution was... I tested this:
export LDAPTLS_REQCERT=allow; ldapsearch -v -H "ldaps://IPADDRESS:636" -b "dc=XX,dc=YY,dc=com" -s sub -D "user@domain.com" -w "pwd" (with the proper values inserted of course)
from the Pf web CLI and I got a lot of output which seemed to indicate that the firewall was able to connect to my DC. I think part of my issue is that the CA cert from the DC does not have an IP in the SAN section, and/or that the Pf cant seem to associate the CA cert CN to an IP, which would make me think the issue is DNS resolution.
Any suggestions on the next move? -
In pfSense, are you defining your server by hostname or IP. If by hostname, you might need to add a host override. I did this under the DNS resolver settings.
I performed the PHP-FPM restart from the console, not from within the web GUI.

@rb_it_pf Thank you so much! I have been wasting away hours/days trying to figure out why LDAPS would not work. Literally running option 16 in the console resolved the issue. Someone should really put this in the documentation. I can't believe that's all I needed to do. You are a life saver!

Hi guys!
It's been a lot since the last response to this.
After updating to 2.7.2, can't get to make work ldaps again (updated from 2.7.0).By running this commands:
setenv LDAPTLS_REQCERT allow ldapsearch -v -H "ldaps://dc1.local:636" -b "dc=local" -s sub -D "username@local" -w "password"seems to work because it shows so much information about my directory.
But it does not work when trying to authenticate on GUI. I have restart PHP-FPM so many times with no success.Please advice.
Thank you!
