VOMS: voms-admin list-suspended-users only shows one suspended certificate

Detailed Description:

Dear VOMS developers,
the command

voms-admin ... list-suspended-users

only shows the first suspended certificate even if a second one is present and suspended.

This makes it difficult to sync a backup VOMS server.

Best,
Andreas
