Hey,
Andrea, I also don't know if we will be able to run a test here without
Geofence. It would be on my own time right now since we battled through the
issue for now. However, I can say we tried to dump a users.xml and
roles.xml while it was running to add the users that way instead of the
REST api and that did however cause an issue when the Authentication Cache
went to run. We also attempted to add one user that way too. Same issue.
I'm not sure if we just hit it with luck on that one user, but it did have
the same effect.
Darell as far as the steps go I will list what we do. Since we are just
pushing GeoFence up for the first time to production our redeploy envolves
a bit and it uses ansible. However, I'll try to list it hope it makes
sense.
Also by doing this the existing users will be lost, so make sure you have a
backup or a way to get them back in.
We currently have two user group services. The default one to keep admin
credentials on. And a second one for our security authentication. It is the
second one that holds all the users.
Steps we took:
1. Stop Tomcat Service
2. Install GeoFence
1. Unarchive
geoserver-{{geofence_version}}-SNAPSHOT-geofence-server-plugin.zip
(This is
the embedded version)
2. Drop them in the tomcat/webapps/geoserver/WEB-INF/lib/
3. Change permissions, owner and group. Which ever one is set for
your tomcat. Permissions 0644
3. Copy Security Files (These are the ones we made modifications for our
setup).
- List of files Under /tomcat/webapps/geoserver/data/security/
- config.xml (This contained our filter chains)
- rest.properties (we made a change here for access on a specific
role)
- /filter/{{our_authentication}}/config.xml
- /role/default/
- /config.xml (this has the change I mentioned, however, we
changed it after deploy because we were using our deploy package)
- /roles.xml
- (the roles.xsd gets generated after first start up)
- /usergroup/{{our_usergroup_name}}/ (this is a new one we created
that is not default.)
- /config.xml
- /users.xml
- /users.xsd
4. Start Tomcat Service
5. Wait For Tomcat to Start
6. Add Data Rules
1. These are our data rules using Geofence REST.
7. After this we go to the admin page and see we have control again.
8. We also ran a test with our admin user, so this might have triggered
the authentication cache. Mabe best to wait 10 minutes till your cache
refreshes before adding the users.
9. Stop Tomcat Service
10. Modify users.xml and roles.xml as mentioned in the last email.
11. Start Tomcat Service
12. Ran our Users script
1. Loop through all users
1. curl REST API to add user
2. curl REST API to associate user with role
3. sleep 1 second (Not sure if we need this. Just noticed without
it, it will chug and possibly run into a stack overflow exception)
And those my friend our the steps we took. Like I said we use ansible, so
we never isolated what exactly caused it to unlock. Actually listing this
out, I am wondering if it was the refresh of users.xml and roles.xml to a
blank state.
Hope that helps.
