[Freeipa-users] ipa: ERROR: did not receive Kerberos credentials

[Rashard.Kelly at sita.aero]

I changed the permissions to world readable to test, afterward I changed 
it back to be readable only by the owner. The problem then reappeared.

[rkelly at replicahostname ~]$ ls -lZa| grep krb
-r--------  root    root    ?                                krb5cc_0
-r--------  xs05144 xs05144 ? krb5cc_1599000020_u5RRhd
-r--------  rkelly  rkelly  ? krb5cc_1599100000_CUkupo
-r--------  rkelly  rkelly  ? krb5cc_1599100000_ZekyY0
-r--------  apache  apache  ?                                krb5cc_48
[rkelly at replicahostname ~]$ od /tmp/krb5cc_1599100000_CUkupo
od: /tmp/krb5cc_1599100000_CUkupo: Permission denied

That's odd. Can you read the file with od?

od /tmp/krb5cc_1599100000_CUkupo

don't send the output just check if it is readable of if od returns an
error as well?

Are there any odd filesystem permission on your klist binary like s-bit
set?

ls -alZ $(which klist)

(her you can send the output :-)
