There was one other small nuance in my test… I used a custom kdc.conf, specified as a bash sub-command:
KRB5_KDC_PROFILE=<(printf …) …
That said, the strace showed it reading from /dev/fd/63 with data returned such as the database_name, so there is no obvious failure on the shell to provide the fd or that the fd was inaccessible. (The only reason I use this syntax to generate a custom KRB5_KDC_PROFILE is to circumvent defining the kadm5_dict_file and loading some of the kadm5 hooks which don’t apply for the kinit operations - this method significantly improves the performance, when it doesn’t sporadically fail.)
