We have Spectrum Scale version 126.96.36.199 running successfully running on a number of redhat 7.5 servers. We have successfully used mmuserauth to enable access to GPFS SMB shares from a Windows AD environment and all is working well
However, we would also like to integrate the Linux GPFS servers with the AD domain for authentication of user logins to the linux GPFS servers. This is so people can use their AD accounts to login to the linux GPFS servers for maintenance etc.
We where initially told this could be done by using the linux realm command to join the AD domain which is one of the usual ways to enable access on a Linux box not running GPFS. However when we tried this on a GPFS environment with SMB shares it broke the SMB shares. (In hindsight it makes sense a server cannot join a AD domain twice !)
Does anyone know how to successfully configure a Linux GPFS server with SMB shares to also use AD for user login authentication ?
Thanks in Advance !
