Finding git credentials in libsecret

[gdt]

To find passwords in libsecret you need to know what attributes to search for. These are often set by some shim but not documented. The attributes tend to vary by shim.

For git's libsecret shim the attributes are: protocol, server, user.

A worked example, the account gdt on git.example.org:

$ secret-tool search --all 'protocol' 'https' 'server' 'git.example.org' 'user' 'gdt'
[/org/freedesktop/secrets/collection/login/123]
label = Git: https://git.example.org/
secret = CvKxlezMsSDuR7piMBTzREJ7l8WL1T
created = 2019-02-01 10:20:34
modified = 2019-02-01 10:20:34
schema = org.gnome.keyring.NetworkPassword
attribute.protocol = https
attribute.server = git.example.org
attribute.user = gdt

Note that the "label" is mere documentation, it's the "attribute" entries which matter.
