RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

                                   ===>      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.

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.
