Description
During tests of gocryptfs 1.7 I found that it didn't work on-top of Lustre with cli2mdt SSK. After a bit of tracing I found that after some setreuid/setregid calls it hadn't got permission to open files.
I've attached a test program that causes the issue. The 501 uid/gid is arbitrary, but it must be run in a directory with with the same uid/gid as chosen here.
When cli2mdt SSK is of it works as expected. When cli2mdt SSK is on it returns:
"open: Permission denied"
Cheers,
Hans Henrik
