[OpenSIPS-Users] OpenSIPs 2.3.3 - cachedb_mongodb - problems with connecting to secure Mongo with the latest mongoc driver

[vladimirk]

Hello,

I am trying to use db_cachedb in conjunction with cachedb_mongodb.
Everything was working fine until we switched to the secured Mongo DB. Now
we switched to use secure mongo instance.

When we use a connection string like below

Config:
loadmodule "cachedb_mongodb.so"
modparam("cachedb_mongodb", "compat_mode_3.0", 1)
loadmodule "db_cachedb.so"
modparam("cachedb_mongodb|db_cachedb", "cachedb_url",
"mongodb:global://myUser:SuperSecret@mongocluster:27017/opensips.col")
modparam("db_cachedb", "cachedb_url",
"mongodb:instance1://myUser:SuperSecret at mongolocal:27017/opensips.col")

 server fails with the following error:

Log:

I have also noticed, that when we have user/password in the URL,
mongo_new_connection receives connection string with the collection name at
the end

Jun  8 19:39:02 [30738] DBG:cachedb_mongodb:mongo_new_connection: cstr:
mongodb://myUser:SuperSecret@mongolocal:27017/opensips.col

This is not happening if I use connection string with authentication.

Can you help to resolve this issue? Can this be resolved with the
configuration only or this looks more like a code issue?

Thanks,
Vladimir
