I am currently trying to setup a redirect on write for an installation of OpenLdap 2.2.
I have two instances running. One is configured to be read-only (only read access, database specified as read-only) and has redirect configured to point to the second instance. The second instance is configured to allow for the desired write permissions.
When I attempt a modify on the first instance it fails as expected but does not send back the referral. Am I missing a piece of the configuration? Am I even on the right path? Any guidance would be greatly appreciated. Thanks.
In the database section of you slapd.conf do you add the redirection like this ? :
updateref "ldap://master-host:port/"
So, it turns out the best way to do this is to go ahead and set up replication using slurpd and point all requests at the slave instance. Unfortunately you can't set up the master and slave on the same host (for obvious reasons, but still), so I had to spin up a second VM to get this going.
Honestly, if I was not trying to replicate a redirect problem it wouldn't be worth it, but I have to duplicate a production issue.
For more information on slapd and specifically slurpd, the OpenLDAP documentation is actually crazy helpful: slurpd config for OpenLDAP 2.2

I am trying to configure or setup the production environment of whatsapp business api as mentioned in the link https://developers.facebook.com/docs/whatsapp/installation/prod-single-instance
I have done everything mentioned in this my dockers are also running on port:9090 as can be seen in the image
still I can't access it. Whenever I try to call https://localhost:9090 the error with "This site can’t be reached" occurs. Whatsapp business api does not have good documentation or tutorials till now. So this site is the only last way for me.
I had a similar problem which could be your case, I saw the docker containers OK but nothing was working. After a day searching I saw where it happened, my problem was I installed mysql MANUALLY (not docker container) in the same instance where docker is running and in db.env I just used 127.0.0.1, this was passed literally to docker container, then looking at a the wait_on_mysql.sh script, the whastapp docker containers were waiting util the mysql ip has conectivity to actually do something and was printing "MySQL is not up yet - sleeping" each second, of course they wouldn't find any conectivity.
Since my instalation is for development, and I am already using such database to other stuff, my solution was to use the 172.17.0.1(docker gateway of the containers) IP instead, then add two sets of network iptables rules to the host to redirect from the docker containers IP to the IP binded by mysql when using such port (3306, the default in my case). After that everything works well. I think there are better solutions, but I didn't want to go far on it, you should evaluate you case if apply.
check the command:
docker-compose logs > debug_output.txt
That gives you insight about whats happening, hope it can helps someone.
I think your setup is already complete. You just need to start with the registration process and start sending messages. The containers are up and running but calling https://localhost:9090 won't send you any response as this is not any specified API endpoint expected to be used.
Since you're using prod single instance, the documentation can be found here which seems pretty straight forward. https://developers.facebook.com/docs/whatsapp/installation/prod-single-instance
You seem to have completed till the 7 steps. The next step can be to perform a health check to make sure it is healthy. The API endpoint for that would be https://localhost:9090/v1/health https://developers.facebook.com/docs/whatsapp/api/health
Has your db also been setup?
I cannot see it in the docker screenshot.
Also - you have to accept the certificate, as it does not have a public CA issues certificate.
I am not familiar with sails.js, nor am I a programmer, but I have been a task assigned to allow a secondary domain to access an existing sails app.
I currently see https://portal.firstdomain.com being served with the corresponding ssl key files setup in config/local.js.
My task would be to allow accessing the same application with https://portal.seconddomain.com. I already configured portal.seconddomain.com to point to the same IP address as portal.firstdomain.com. I am getting a page with a configuration error message. So I guess I am reaching sails.js. There is no other webserver active on this IP address. What is puzzling to me is that firstdomain.com is not mentioned anywhere in any configuration file. Except perhaps indirectly in the ssl files which are imported in config/local.js...
Where would I find the right documentation or hints which would explain to me what to do? Any hint is very appreciated.

I try to setup an OpenLDAP-Server that I can use as backend for a WebSSO (LemonLDAP::NG). This specific WebSSO allows to store the sessions inside the LDAP backend.
My problem is that it seems that whenever I connect to the LDAP backend to store session data ~1 out of 10 times it works, the other times LDAP rejects the authentication.
Logs for failed attempts and for successful attempts can be found here
As you can see the maker of LemonLDAP::NG thinks the error is within OpenLDAP (or my configuration of OpenLDAP). I'm out of ideas and open to suggestions.
Looks like someone changes OpenLDAP DB during your session. Don't you have any processes with access to MDB file except this instance of OpenLDAP?
It may be slapadd/slapmodify/2nd slapd instance with the same directory value in config.
If not, could you show your slapd.conf (don't forget to change rootpw)
I have a problem trying to implement a mongodb replica set as a worker role instance in Windows Azure. In the Windows Azure portal, one of the instances is shown as busy with the status:
Waiting for role to start... Calling OnRoleStart()
I have checked all the settings and everything seems to be ok, what could the problem be?
Denis Markelov's blog post helped me solve this problem. The solution is mainly his, however I had to take an extra step to get it to work and thought others might find it useful.
Solution from blog:
Windows Azure reuses virtual machines for roles, so after a fresh
deployment on a hard drive you can find files that were created during
previous sessions. If MongoDB was terminated improperly - there might
be a lock file ("persisted mutex" analogue), because of which MongoDB
refuses to start. It is located at the drive with a label
"WindowsAzureDrive" (say it is F:), at the path:
F:\data\mongod.lock
In the case of a production use this situation might require a
recovery procedures, but if you are just in the process of initial
setup - it is safe to remove this file, letting MongoDB to start
again.
I was having this problem and did as suggested, however I was still having the same problem. So I took a look at the log file at
C:\Resources\Directory\.MongoDB.WindowsAzure.MongoDBRole.MongodLogDir\mongod.txt
And saw that another file was also giving an error. In order to fix the problem, you also have to delete the file local.ns in the same directory as mongod.lock.
How can I get log information from PostgreSQl server?
I found ability to watch it in pgAdmin Tolls->ServerStatus. Is there a SQL way, or API, or consol way, to show content of log file(s)?
Thanks.
I am command line addict, so I prefer “console” way.
Where you find logs and what will be inside those depends on how you've configured your PostgreSQL cluster. This the first thing I change after creating a new cluster, so that I get all the information I need and in the expected location.
Please, review your $PGDATA/postgresql.conf file for your current settings and adjust them in the appropriate way.
The adminpack extension is the one providing the useful info behind pgAdmin3's server status functionality.
