Add support for registering public user SSH keys in LDAP

Reported by: strk Owned by: sac@…
Priority: normal Milestone: Sysadmin Contract 2020-I
Component: SysAdmin Keywords: ldap


For better security, it would be useful to let OSGeo members register their public key within the LDAP database, then those keys could be accepted for logging into services.

Okay I've changed our ldap to support installing keys

and changed the edit page here:

So you can put in your public key.

Right now I only have and setup to read the keys from ldap for ssh.

Going to do that next on (aka

Once that is in place, the new steps for people to be able to ssh into download will be:

  1. Get added to ldap shell group - same
  2. Instead of having to bother a sac team member to install your keys, you'd go to

and paste your public key in there.

Okay made the same change on download and deleted my .ssh folder to confirm it works.

I've updated the instructions here

Cool! Can users have multiple SSH keys ? As I know for sure I use multiple devices each with a different ssh key...

comment:6 by robe, 4 years ago

I read it's possible but not sure how it's done. Maybe it's as simple as pasting multiple keys in the SSH Public Key field.

It should be tested, and if it works, advertised in the form as a possiblity.

comment:8 by strk, 4 years ago

I've tested: you can store multiple ssh keys in that form. I've updated it accordingly. Great! Now on to use it from Gitea !

strk if you really want to use the port 22 we could allocate a separate IP for trac. We have two for osgeo7 at the moment. secure has an ip just for use for the ldap port. We could use the same ip for gitea I suppose and expose the port 22 on it like we have on download just for ssh key access.

Looking at gitea - aside from enabling the ssh, looks like we just need to specify the sshpubkey field (which it defaults anyway)
