Re: Antw: [EXT] invalid opcode

[Stefan Kania]

Another strange thing about passwords on the same machine. As I told you before, we switch to ssha as paswordhash. The server works. But now we start to create new passwords with "slappasswd", we are getting a {SSHA}<hash>. But when change the password via ldif. The password is never valid. We did it several times, and it's always the same. But when changing passwords via LDAP account manager, the password works, them when creating the SSHA-password with:

A log time ago I read something about problems with Entropy in vmWare but I can't remember what it was. Could this be my problem with argon2 and slappasswd?

I think I found the problem:



Can someone confirm it?

Thank's to Ulrich for pushing me in the right direction ;-)

The host has a 12 year old CPU Intel Xeon E5-2630 . Together with argon2 as passwordhash there is a problem. As soon as I switrch to SSHA everything is working fine.

Maybe examine the compiler flags, compiler version and CPU running the binary.

I use the symas-packeages from repository. I did not compile it on my own ;-)
