transsib ... that file is provided by sys-auth/nss_ldap. You should have this package if you're planning authenticating local logins via ldap (though I'm not sure openldap pulls it in).

Title Migration required for OpenSSH with LDAP
Author Thomas Deutschmann <whissi@gentoo.org>
Posted 2018-08-07
Revision 1
If your sshd authenticates against LDAP, you have to migrate your
current setup to a new one using sshd's "AuthorizedKeysCommand" option and
a wrapper provided by packages like the new sys-auth/ssh-ldap-pubkey or
sys-auth/sakcl because beginning with net-misc/openssh-7.7_p1, OpenSSH-LPK
patch set is deprecated and no longer applies.
We have created a short migration guide in the Wiki [1] for more details.

@fedeliallalinea
I got that (see my posting above), compiled the wrapper; I now see I do not have the ldap.conf file.
@khayyam
thanks, sys-auth/nss_ldap is not on the system; compiling now.
/etc/ldap.conf is present now, continuing but

I think you missed the point: there is nothing to migrate if you don't use it. |

you need to issue the command with the word python at the beginning like so:
| Code: | | python ssh-ldap-pubkey list |
Since ssh-ldap-pubkey is a python script, your terminal doesn't automatically recognize you're running a python script, therefore you must "tell" terminal to use python in order to run script file |

In this case I can remove the new packages and just ignore the news item.
jhon987, the wiki does not mention it. My system does not seem to need migrating.

Yeah, I know it doesn't but I wrote it still because that's what one needs to do when they encounter errors such as you did. (So it might be useful to you in the future, or for someone else who would come across this thread)
I guess the person who wrote the wiki article has his terminal automatically assume python script or something... |

| If the system did not recognize it as a Python script, how did he get a Python3.6 traceback telling him that the LDAP server is unreachable? |

I don't think it's a python traceback but a bash traceback. The ssh-ldap-pubkey script is found inside the python directory: /usr/lib/python-exec/python3.6/ssh-ldap-pubkey
and so the the functions inside that script are pointing to: /usr/lib64/python3.6/site-packages/ldap/ldapobject.py
however since the python interpreter (binary) isn't being utilized, that eventually leads to the errors he's getting.
Basically since the shebang: #!/usr/bin/env python is stated at the beginning of the file - terminal should recognize it's a python script, perhaps terminal defaults to the python interpreter version 2(.7) (maybe it is a python traceback) and so the script isn't functioning, perhaps the shebang should be changed to #!/usr/bin/env python3
I'm saying this from my own experience as well, I used same command and got same errors, yet once I used python before the command - suddenly I got meaningful output. |

| Bash does not produce tracebacks like that. It seems unlikely to be a Python version problem, since the error message specifically states that it failed to contact the LDAP server. |
