[389-users] Re: Enable SSHA hashing scheme

Actually I just upgrade the system from centos7 to almalinux9 using elevate. Essentially this is similar to a copy of the /etc/dirsrv and /var/lib/dirsrv directories and started the new ldapserver. 

Directly afterwards I was not able to login using the cn=Directory Manager. I checked the hashed password in the dse.ldif  file (cn=config) using pwdhash. It was ok. 

Once I changed the password of the directory manager in the dse.ldif file after stopping the 389ds using PBKDF2-SHA512 hash, the Directory Manager was able to login. Other users required a reset of their password as well for successful login. But since I do not have access to all passwords I would rather reuse the old tree.

The nsslapd-allow-hashed-passwords is set to on.

Therefore I doubt that I have double hashed passwords. For the case of the Directory Manager I am positive.

And yes, dsconf lists SSHA in my case as well. Any ideas why this is not working?

My passwordpolicy is quite open:

Global Password Policy: cn=config
------------------------------------
nsslapd-pwpolicy-local: off
passwordstoragescheme: SSHA512
passwordchange: on
passwordmustchange: off
passwordhistory: off

Hi there,
I am trying to update a ldap tree from 389ds 1.3.11 (centos7) to 2.4.5 (almalinux9). After migrating the tree all passwords stop working including the Directory Manager. The old tree used SSHA. Setting the rootpwstoragescheme does not help for the Directory Manager. Only manually resetting the passwords using pwdhash in the dse.ldif file and using a PBKDF2-SHA512 password works. Is there a way to enable the old SSHA scheme?

SSHA is still supported in the latest 389-DS:
# dsconf localhost pwpolicy list-schemes | grep SSHA
SSHA
SSHA256
SSHA384
SSHA512

How did you perform the migration? Via replication or export/import?

What is the value of nsslapd-allow-hashed-passwords in cn=config?

I suspect that your passwords after the migration might be doubly hashed instead of imported as is.

 

Kind regards,
Ralf
