When creating a user, a password hash is used and the "digestPassword" option is set to "false". By default in Mongodb 4.x the parameter "mechanisms" is set to ["SCRAM-SHA-1","SCRAM-SHA-256"], but according to the documentation (https://docs.mongodb.com/manual/reference/command/createUser/ ) for SCRAM-SHA-256 "digestPassword" cannot be "false". Example: $ mongo admin --quiet --host 127.0.0.1:27017 --eval "load('/root/.mongorc.js'); db.runCommand({\"createUser\":\"test\",\"pwd\":\"398fefcb5925a718fd0c812bbeb7e101\",\"customData\":{\"createdBy\":\"Puppet Mongodb_user['test']\"},\"roles\":[\"clusterMonitor\"],\"digestPassword\":false})" output: { "ok" : 0, "errmsg" : "Use of SCRAM-SHA-256 requires undigested passwords", "code" : 2, "codeName" : "BadValue" } If you remove SCRAM-SHA-256, it works correctly: $ mongo admin --quiet --host 127.0.0.1:27017 --eval "load('/root/.mongorc.js'); db.runCommand({\"createUser\":\"test\",\"pwd\":\"398fefcb5925a718fd0c812bbeb7e101\",\"customData\":{\"createdBy\":\"Puppet Mongodb_user['test']\"},\"roles\":[\"clusterMonitor\"],\"digestPassword\":false, \"mechanisms\":[\"SCRAM-SHA-1\"]})" output: { "ok" : 1 } Thus, you need to add SCRAM-SHA-256 support, not use "password_hash" and set digestPassword to "true", or just use SCRAM-SHA-1, which seemed to me the simplest solution, which does not require global changes.
