Well yes, the group system:firstname.lastname@example.org does exist:
[root@afs1c afs]# pts listentries -groups -noauth
Name ID Owner Creator
system:administrators -204 -204 -204
system:backup -205 -204 -204
system:anyuser -101 -204 -204
system:authuser -102 -204 -204
system:ptsviewers -203 -204 -204
system:email@example.com -207 -204 2
Also, system:firstname.lastname@example.org was created by 2, which is me as admin, so
it was there before my aklog as foreign user. Is the foreign-realm
group something that needs to be set in advance, or is that part of the
automatic registration thing?
And yes, as foreign user email@example.com, I lack the "rlidwka" rights to
the cell directory /afs/afs1.bedrock.iu.edu. All I can do is "rl"
