Hi, thank you for this report. It seems that FreeRDP does not limit length of passwords. Just some of its clients limit it to 512 characters. Sysadmin for a medium sized paying RHEL customer here. I have a user complaining about this, so... +1 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHSA-2019:2157 |
Description of problem: - vinagre does not accept extra long passwords. Version-Release number of selected component (if applicable): - all versions How reproducible: - 100% Steps to Reproduce: 1. Run Vinagre 2. attempt to establish an RDP connection using a password greater than 20 characters 3. Actual results: - cannot use passwords greater than 20 characters Expected results: - valid passwords are accepted regardless of length Additional info: From source: static gboolean frdp_authenticate (freerdp *instance, char **username, char **password, char **domain) { VinagreTab *tab = VINAGRE_TAB (((frdpContext *) instance->context)->rdp_tab); VinagreRdpTab *rdp_tab = VINAGRE_RDP_TAB (tab); VinagreRdpTabPrivate *priv = rdp_tab->priv; VinagreConnection *conn = vinagre_tab_get_conn (tab); GtkWindow *window = GTK_WINDOW (vinagre_tab_get_window (tab)); gboolean save_in_keyring = FALSE; gchar *keyring_domain = NULL; gchar *keyring_username = NULL; gchar *keyring_password = NULL; .... if (vinagre_utils_request_credential (window, "RDP", vinagre_connection_get_host (conn), vinagre_connection_get_domain (conn), vinagre_connection_get_username (conn), TRUE, TRUE, TRUE, ===> 20, 0 // hardcoded to 20 chars domain, username, password, &save_in_keyring)) ---------------- invoking freerdp directly does not exhibit the password length limitation, so this is merely an arbitrary hardcoded limit of 20 characters, and I am not aware of any password limit on RDP outside of the MS Windows maximums, which for Windows 10 are as follows: Windows represents passwords in 256-character UNICODE strings. The logon dialog is limited to 127 characters, however. Source: http://www.thewindowsclub.com/maximum-length-of-password-windows-10
