Configuring NIS-based authentication
The Network Information Service (NIS)-based authentication is useful in NFS only environment where NIS acts as an ID mapping server and also used for netgroups. When file access is configured with NIS, SMB access cannot be enabled.
Ensure that you have the following details before you start
NIS-based authentication:
- NIS server name. This is case-specific
- IP address or host name of the NIS server
- Primary DNS is added in the /etc/resolv.conf file on all the protocol nodes. It resolves the authentication server system with which the IBM Spectrum Scale™ system is configured. The manual changes done to the configuration files might get overwritten by the Operating System's network manager. So, ensure that the DNS configuration is persistent even after you restart the system. For more information on the circumstances where the configuration files are overwritten, refer the corresponding Operating System documentation.
You need to run the mmuserauth service create command
with the following mandatory parameters to configure NIS as the authentication
method:
- --type nis
- --data-access-method file
- --domain domainName
- --servers comma-delimited IP address or host name
Provides an example on how to configure NIS as the authentication
method for file access.
