Subject: [PATCH 1/2] cli_credentials_parse_string: fix parsing of principals
|
||||
|
||||
When parsing a principal-like name, user name was left with full
|
||||
principal instead of taking only the left part before '@' sign.
|
||||
|
||||
>>> from samba import credentials
|
||||
>>> t = credentials.Credentials()
|
||||
>>> t.parse_string('admin@realm.test', credentials.SPECIFIED)
|
||||
>>> t.get_username()
|
||||
'admin@realm.test'
|
||||
|
||||
The issue is that cli_credentials_set_username() does a talloc_strdup()
|
||||
of the argument, so we need to change order of assignment to allow
|
||||
talloc_strdup() to copy the right part of the string.

|

When using security tab in Windows Explorer, a lookup over a trusted
|
||||
forest might come as realm\name instead of NetBIOS domain name:

Allow this lookup using realm to be done against primary domain.
|

|

Refactor user name parsing code to reuse cli_credentials_* API to be
|
||||
consistent with other places. cli_credentials_parse_string() handles
|
||||
both domain and realm-based user name variants.
