Hi Lena and Christian, Thank you for your input and for pointing out that this functionality will "naturally" be available in 26.04 once upstream provides it.
I would kindly like to ask for your support regarding one point: since using PBKDF2 with a configurable number of iterations is quite important for meeting security requirements (including in some cases FIPS 140-3), do you think it would be possible to introduce this option also in Ubuntu 24.04 (perhaps via a maintenance update)? Best regards, Filippo -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openldap in Ubuntu. https://bugs.launchpad.net/bugs/2125685 Title: pbkdf2 module not make iterations configurable and FIPS 140-3 Status in openldap package in Ubuntu: Confirmed Status in openldap source package in Jammy: Confirmed Status in openldap source package in Noble: Confirmed Status in openldap source package in Plucky: Confirmed Status in openldap source package in Questing: Confirmed Bug description: On Ubuntu 24.04, the OpenLDAP package ships with the library /usr/lib/ldap/pw-pbkdf2.so. While this module works for generating PBKDF2-SHA512 password hashes, it does not provide an option to configure the number of iterations. For example: slappasswd -o module-load=pw-pbkdf2.so -h {PBKDF2-SHA512} generates a hash with a fixed iteration count (e.g. 10000) and does not accept parameters to increase it. In contrast, the upstream contrib module passwd/pbkdf2 on https://git.openldap.org/openldap/openldap/-/tree/master/contrib/slapd- modules/passwd/pbkdf2 supports the iteration count option and allows administrators to configure it. moduleload pw-pbkdf2.so [iterations] Steps to reproduce: Install OpenLDAP on Ubuntu 24.04. (slapd and slapd-contrib pakages) Run slappasswd -o module-load=pw-pbkdf2.la -h {PBKDF2} -s secret {PBKDF2}10000$ZvU8GRSybbefW48n8BeyuA$XE1t4W09ZP0z8zmLVb/SbwaOl2Y Expected behavior: The pw-pbkdf2.so module should support configuration of the iteration count, as provided in the upstream passwd/pbkdf2 contrib module. Actual behavior: Iteration count is hardcoded (default: 10000), and cannot be changed. Impact: Without the ability to configure the iteration count, it is not possible to meet current security best practices or achieve compliance with FIPS 140-3, which requires configurable and sufficiently high iteration counts for PBKDF2.
