Subject: sss_client: avoid leaking file descriptors
|
|
|
|
If a pam or nss module is dlcolse()d and unloaded we were leaking
|
|
the file descriptor used to communicate to sssd in the process.
|
|
|
|
Make sure the fucntion used to close the socket file descriptor is
|
|
called on dlclose()
|
|
|
|
