Hi Viktor,
thanks a lot for testing and finding that. I did not catch that.
Thanks for the support. I will try to use the recreated instance.
Kind regards,
Ralf

Essentially this is similar to a copy of the /etc/dirsrv and /var/lib/dirsrv directories and started the new ldapserver.We don't support or test in-place upgrades (leapp/elevate) and recommend using export/import or replication methods.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?Do you see any errors regarding NSS in the errors log?NSS in EL7 was using an old datbase format, and if you just copied it to EL9, it's very likely to fail initialization.My passwordpolicy is quite open:Global Password Policy: cn=config

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?
# dsconf localhost pwpolicy list-schemes | grep SSHA
SSHA
SSHA256
SSHA384
SSHA512How 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
