Hello all,

I compiled pw-argon2 for OpenLDAP 2.4.44 (running on CentOS 7) and configured the directory to use the {ARGON2} password scheme. Everything works fine, only it seems the parallelism remains 1 whatever parameter I give when I load the module. Memory usage and number of iterations do follow the values I give at module load.

Here's cn=module,cn=config:

dn: cn=module{0},cn=config objectClass: olcModuleList cn: module{0} olcModulePath: /usr/lib64/openldap olcModuleLoad: {0}ppolicy olcModuleLoad: {1}syncprov olcModuleLoad: {2}accesslog olcModuleLoad: {3}pw-argon2 m=4096 t=8 p=8

And here's (the beginning of) a password which has been changed using ldappasswd (base64 decoded value obtained with ldapsearch): {ARGON2}$argon2id$v=19$m=4096,t=8,p=1$7KxBUtls1NNPDK4Q4f+.......

What am I missing?

I don't know if this is relevant, libsodium version is 1.0.18 and I compiled pw-argon2 using the libraries provided by openldap-2.4.44-21.el7_6.src.rpm. Let me know if I need to provide other configuration elements.

Two more points: - the pw-argon2 man page (and README file of the module) examples seem to be obtained using argon2i, while the module uses argon2id; - what salt length is used?

Thanks for your help, best regards,

Manuela
