Hello,

According to: servers/slapd/pwmods/README.argon2

Building --------

1) Customize the OPENLDAP variable in Makefile to point to the OpenLDAP source root.

For initial testing you might also want to edit DEFS to define SLAPD_ARGON2_DEBUG, which enables logging to stderr (don't leave this on in production, as it prints passwords in cleartext).

2) Run 'make' to produce argon2.so

3) Copy argon2.so somewhere permanent.

4) Edit your slapd.conf (eg. /etc/ldap/slapd.conf), and add:

moduleload ...path/to/argon2.so

5) Restart slapd.

When I run make from within servers/slapd/pwmods/ I get the following error:

[user@machine openldap-2.6.4]# cd servers/slapd/pwmods/ [user@machine pwmods]# make make: *** No rule to make target 'dummyvalue', needed by 'all-common'. Stop.

I’m not sure what “dummyvalue” is supposed to be so I commented out line 288 in servers/slapd/pwmods/Makefile

# LIBRARY = dummyvalue

And get this error:

[user@ machine pwmods]# make /bin/sh ../../../libtool --tag=disable-static --mode=compile cc -g -O2 -I../../../include -I../../../include -I.. -I./.. -DSLAPD_IMPORT -c version.c libtool: compile: cc -g -O2 -I../../../include -I../../../include -I.. -I./.. -DSLAPD_IMPORT -c version.c -fPIC -DPIC -o .libs/version.o version.c:1:6: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘:’ token usage: mkversion [-c] [-s] [-p package] [-v version] application ^ make: *** [Makefile:310: version.lo] Error 1

Any help in generating argon2.so would be greatly appreciated.

If I’m somehow getting deeper in the weeds than I need to with the new OpenLDAP version 2.6.4 in order to support {ARGON2} hashes please let me know. Import of my slapd.ldif file is bonking on:

olcPasswordHash: {ARGON2}

So as with previous versions of OpenLDAP I assumed I would need to build and load the argon2 module manually.

Sincerely, Scott Classen
