Subject: [PATCH] Correctly import "service@" GSS host-based name
|
|
|
|
The intended way to specify only a service in a GSS host-based name is
|
|
to omit the "@" separator. Some applications include the separator
|
|
but no hostname, and this happened to yield wildcard hostname behavior
|
|
prior to commit 996353767fe8afa7f67a3b5b465e4d70e18bad7c when
|
|
shortname qualification was added. To restore this behavior, check in
|
|
parse_hostbased() that at least one character is present after the "@"
|
|
separator before copying the hostname. Add a test case to t_gssapi.py.
