CentOS 7, SSSD against LDAP: finds user but will not log them in, "Authentication failure" when trying to su
Hi,
I am trying to get SSSD to authenticate against an OpenLDAP directory. I have "debug_level" turned up to 10 but have not been able to figure out what the problem is based on the log.
On an Ubuntu 22.04 system I have found that something with TLS is broken when it tries to connect to OpenLDAP, which is why it has failed on that system -- I think this is related to the OS moving to OpenSSL 3 but have not been able to figure out how to fix it.
On this CentOS 7 system, you can see that it can find the user, can get properties from the user, but still fails the user login without, as far as I can tell, explaining why.
I have pasted our sssd.conf below, and here is a link to my Nextcloud instance where I am hosting the relevant portion of the log (it was too big for me to be able to paste it into Pastebin): https://checkwithscience.com/index.php/s/e7mXKAzcq87q6HD https://checkwithscience.com/index.php/s/e7mXKAzcq87q6HD
Hoping someone can help us get to the bottom of this.
Thanks.

Hi Sumit,
Thank you! You made me realize I never updated PAM using authconfig. `sudo authconfig --enablesssdauth --enablesssd --updateall --enablemkhomedir` took care of it.
Do you have any insights as to what is going on with the newer (Ubuntu 22.04) machine's attempts to authenticate? SSSD logs are pretty clear that there is an "unknown error" with TLS communication despite the OpenLDAP server appearing to communicate normally -- OpenSSL 3.0 freezes, basically, while trying to connect, as seen here:

^-- it stops there. I understand hanging and waiting for further communication is normal behavior , but I don't think this is where it's supposed to stop.
Obviously, CentOS 7 with its older version of SSL has no trouble connecting. One difference is that on CentOS 7 it says "Secure Renegotiation IS supported."
TIA for any help.
Thanks, Jarett

Hi Sumit,
Thank you! You made me realize I never updated PAM using authconfig. `sudo authconfig --enablesssdauth --enablesssd --updateall --enablemkhomedir` took care of it.
Do you have any insights as to what is going on with the newer (Ubuntu 22.04) machine's attempts to authenticate? SSSD logs are pretty clear that there is an "unknown error" with TLS communication despite the OpenLDAP server appearing to communicate normally -- OpenSSL 3.0 freezes, basically, while trying to connect, as seen here:

If you look at it with `openssl s_client`, it freezes right here:
Hi,
I think your 'openssl s_client' output looks ok.
I would assume that you are not only using a newer version of OpenSSL but a newer version of OpenLDAP as well which might be more picky when it comes to TLS and certificates.
First I would suggest to not use the IP address of the LDAP server in sssd.conf but the fully qualified name ldapserver00.clab.lab, the one from the CN of your certificate.
If this does not help, please add 'ldap_library_debug_level = -1' to the [domain/...] section of sssd.conf to get the full OpenLDAP debug output which might help to better understand what is missing.
Additionally you can check if the new option TLS_REQSAN is set in ldap.conf on the client to 'demand' or 'hard' which would make the client require a SAN (subject alternative name) in the certificate which yours does not have.
HTH
bye, Sumit

^-- it stops there. I understand hanging and waiting for further communication is normal behavior , but I don't think this is where it's supposed to stop.
Obviously, CentOS 7 with its older version of SSL has no trouble connecting. One difference is that on CentOS 7 it says "Secure Renegotiation IS supported."
TIA for any help.
Thanks, Jarett

Hi,
I am trying to get SSSD to authenticate against an OpenLDAP directory. I have "debug_level" turned up to 10 but have not been able to figure out what the problem is based on the log.
On an Ubuntu 22.04 system I have found that something with TLS is broken when it tries to connect to OpenLDAP, which is why it has failed on that system -- I think this is related to the OS moving to OpenSSL 3 but have not been able to figure out how to fix it.
On this CentOS 7 system, you can see that it can find the user, can get properties from the user, but still fails the user login without, as far as I can tell, explaining why.
I have pasted our sssd.conf below, and here is a link to my Nextcloud instance where I am hosting the relevant portion of the log (it was too big for me to be able to paste it into Pastebin): https://checkwithscience.com/index.php/s/e7mXKAzcq87q6HD https://checkwithscience.com/index.php/s/e7mXKAzcq87q6HD<https://checkwithscience.com/index.php/s/e7mXKAzcq87q6HD https://checkwithscience.com/index.php/s/e7mXKAzcq87q6HD>
Hi,
there is no authentication attempt covered in the log file. Are you sure pam_sss.so is included in your PAM configuration and called for the specific user?

Off the top, the LDAP server can not resolve in DNS, so it's setting the LDAP server name to the IP, the IP is not in your cert as a SAN that I can see.

You made me realize I never updated PAM using authconfig. `sudo authconfig --enablesssdauth --enablesssd --updateall --enablemkhomedir` took care of it. Do you have any insights as to what is going on with the newer (Ubuntu 22.04) machine's attempts to authenticate? SSSD logs are pretty clear that there is an "unknown error" with TLS communication despite the OpenLDAP server appearing to communicate normally -- OpenSSL 3.0 freezes, basically, while trying to connect, as seen here: (2022-12-07 7:17:24): [be[default]] [check_if_online_delayed] (0x2000): [RID#1010] Trying to go back online!

I understand hanging and waiting for further communication is normal behavior , but I don't think this is where it's supposed to stop. Obviously, CentOS 7 with its older version of SSL has no trouble connecting. One difference is that on CentOS 7 it says "Secure Renegotiation IS supported." TIA for any help.

I have "debug_level" turned up to 10 but have not been able to figure out what the problem is based on the log. On an Ubuntu 22.04 system I have found that something with TLS is broken when it tries to connect to OpenLDAP, which is why it has failed on that system -- I think this is related to the OS moving to OpenSSL 3 but have not been able to figure out how to fix it. On this CentOS 7 system, you can see that it can find the user, can get properties from the user, but still fails the user login without, as far as I can tell, explaining why.
