What is Casdoor?

An identity platform tightening server-side enforcement one micro-release at a time.

Casdoor is a self-hosted single sign-on and identity management service covering OAuth, LDAP, MFA and user administration. It releases continuously — four tags landed within eighty minutes on 16 August — with each carrying a single commit, so a version number here marks one change rather than a bundle.

What is Fail2Ban?

Fail2Ban finally ships 1.1.1 after 14 months in beta, with a botched deb package on the way out the door

Fail2Ban watches log files for authentication failures and bans the offending addresses through the local firewall. It remains a default component of Linux server hardening, and its release cadence has never matched that prominence — six releases in the eight years before this one. The 1.1.1 final has now landed, closing a beta that had sat unfinished since June 2025, and it installs a systemd-managed socket rather than relying solely on the daemon's own startup.

Casdoor vs Fail2Ban: editorial side-by-side

Casdoor
INFRA · APIS
5.0

An identity platform tightening server-side enforcement one micro-release at a time.

◆ Current state

Casdoor is a self-hosted single sign-on and identity management service covering OAuth, LDAP, MFA and user administration. It releases continuously — four tags landed within eighty minutes on 16 August — with each carrying a single commit, so a version number here marks one change rather than a bundle.

◆ Where it's heading

The recent run is almost entirely about moving enforcement to where it cannot be bypassed. Password update and MFA setup are now enforced server-side, the column whitelist is respected when an admin updates a user, and sessions and tokens are revoked when a user is forbidden. Each of these closes a gap where the client or an administrative path could sidestep a rule the product already claimed to apply. LDAP search by uidNumber and gidNumber and phone number normalisation round out the same period.

◆ Prediction

Expect the per-commit release cadence to continue, with further authorization-boundary fixes given three of the last five entries address exactly that. Nothing here signals a larger architectural change.

Fail2Ban finally ships 1.1.1 after 14 months in beta, with a botched deb package on the way out the door

◆ Current state

Fail2Ban watches log files for authentication failures and bans the offending addresses through the local firewall. It remains a default component of Linux server hardening, and its release cadence has never matched that prominence — six releases in the eight years before this one. The 1.1.1 final has now landed, closing a beta that had sat unfinished since June 2025, and it installs a systemd-managed socket rather than relying solely on the daemon's own startup.

◆ Where it's heading

The pattern is long silences broken by releases that mostly absorb external change — Python 3.12 and 3.13 compatibility in 1.1.0, a Dovecot filter regression in 1.0.2 — with the substance deferred to a ChangeLog the feed does not carry. What is different this time is the contributor list, which runs to a dozen first-time contributors, suggesting the delay was throughput rather than abandonment. The release also had to be re-cut: the first Debian package shipped with wrong paths from a missing systemd-dev build dependency and was pulled and replaced.

◆ Prediction

Given the beta-to-final gap just closed and the volume of first-time contributors merged into it, the useful thing to watch is whether the next release arrives in months rather than years; the entries do not indicate what it would contain.
