What Should I Do If Invalid Authentication Is Reported When I Submit an Order for Purchasing an MRS Cluster?

Question:

What Should I Do If Invalid Authentication Is Reported When I Submit an Order for Purchasing an MRS Cluster?

Answer:

1. Contact the administrator to check API request logs. The alarm information is as follows: IAM users have not been assigned the mrs:cluster:create permission in the fine-grained policy.
2. The IAM user belongs to multiple user groups, and different default MRS policies are assigned to these user groups. Low-permission policies are preferentially matched. This policy does not contain the mrs:cluster:create permission. As a result, the cluster creation operation cannot be submitted, and error 401 is reported.
3. After the user is removed from the user group corresponding to the low-permission policy, the cluster purchase order can be submitted.
