mongoexport遭遇Authentication failed
今天使用mongoexport工具导出数据，遇到权限不足报错：
[host]$mongoexport -h 10.31.11.190:23820 -udbmgr -pMgr2mgdb -d rcmp -c policydata --limit 20000 -o policydata.dat
2017-04-25T11:02:06.599+0800 Failed: error connecting to db server: server returned error on SASL authentication step: Authentication failed.
查询用户权限，是有root权限的
mongos> use admin
switched to db admin
mongos> db.system.users.find({user:"dbmgr"})
{ "_id" : "admin.dbmgr", "user" : "dbmgr", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "bVTTgVm0VVByspn7nANRzA==", "storedKey" : "kLS7xO2cJFwSx3qrf4Hz/fNeZaI=", "serverKey" : "QRhOc5+/BmVlPu/58q+MJlNLXmI=" } }, "roles" : [ { "role" : "root", "db" : "admin" } ] }
