SLAPPW-ARGON2(5) File Formats Manual SLAPPW-ARGON2(5)
slappw-argon2 - Argon2 password module to slapd
ETCDIR/slapd.conf
moduleload argon2 [<parameters>]
The argon2 module to slapd(8) provides support for the use of the
key derivation function Argon2, that was selected as the winner
of the Password Hashing Competition in July 2015, in hashed
passwords in OpenLDAP.
It does so by providing the additional password scheme {ARGON2}
for use in slapd.
The argon2 module does not need any configuration, but it can be
configured by giving the following parameters:
m=<memory>
Set memory usage to <memory> kiB.
p=<parallelism>
Set parallelism to <parallelism> threads. Currently
supported only when linked with libargon2.
t=<iterations>
Set the number of iterations to <iterations>.
These replace defaults when preparing hashes for new passwords
where possible.
After loading the module, the password scheme {ARGON2} will be
recognised in values of the userPassword attribute.
You can then instruct OpenLDAP to use this scheme when processing
the LDAPv3 Password Modify (RFC 3062) extended operations by
using the password-hash option in slapd.conf(5):
password-hash {ARGON2}
NOTES
If you want to use the scheme described here with slappasswd(8),
remember to load the module using its command line options. The
relevant option/value is:
-o module-load=argon2
Or if non-default parameters are required:
-o module-load="argon2 [<param>...]"
Depending on argon2's location, you may also need:
-o module-path=pathspec
Both userPassword LDAP attributes below encode the password
'secret' using different salts:
userPassword: {ARGON2}$argon2i$v=19$m=4096,t=3,p=1$c2FsdHNhbHQ$DKlexoEJUoZTmkAAC3SaMWk30El9/RvVhlqGo6afIng
userPassword: {ARGON2}$argon2i$v=19$m=4096,t=3,p=1$c2FsdHNhbHRzYWx0$qOCkx9nMeFlaGOO4DUmPDgrlUbgMMuO9T1+vQCFuyzw
