VOMS Group Managers

There is now a new GroupManager role available for the VO. This role is used like the VO-Admin role was previously in VOMRS, so as to internally to tag the group managers.

For each group to which we want to delegate management, we need to add an ACL for both the group and the VO root. The ACLs can be granted via the this link:

VOMS Admin Management

New requests for VO membership should be verified for existing CERN accounts, and prevented from creating duplicate memberships, before approval.

This procedure is intended only for VO administrators. It may be useful to open multiple browser windows for each of the necessary sites (VOMS Admin, CERN Accounts, etc.).

SFTP gateways - Transfer files using SFTP gateways.

Information on the SFTP gateways - 

Users should use sftp.sdcc.bnl.gov to access the sftp gateways and transfer files. 

There are many graphical clients available like WinSCP that users can download and install. 

SSH keys should be used to access the sftp gateways. 

GPFS and NFS home directory filesystems are available through the SFTP gateways.  

The gateways do not allow interactive access or allow scp transfers for security reasons.
