From 341996248e4d720556689e5fb3da7a408cf94228 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 27 Jul 2023 12:07:48 -0400 Subject: [PATCH] Raise fixed token-length limit in hba.c. Historically, hba.c limited tokens in the authentication configuration files (pg_hba.conf and pg_ident.conf) to less than 256 bytes. We have seen a few reports of this limit causing problems; notably, for moderately-complex LDAP configurations. Increase the limit to 10240 bytes as a low-risk stop-gap solution. In v13 and earlier, this also requires raising MAX_LINE, the limit on overall line length. I'm hesitant to make this code consume too much stack space, so I only raised that to 20480 bytes.
