No password for the « admin » UNIX user



If I try to install any application, custom or not, I get a failed. “Installation failed” on red. And when use the log button I can get the message Pas de mot de passe pour l’utilisateur « admin »

If I try from command line, same, it’s not working.
Example with transmission from cli :

 root@kraton:~# yunohost app install transmission
chown: spec non valide: « admin: »
chown: spec non valide: « admin: »
Choose a domain for Transmission :
Choose a path for Transmission (default: /torrent) : 
Exécution du script...
Pas de mot de passe pour l'utilisateur « admin »
Erreur : Échec de l'installation

End of log file :

Are you able to connect via SSH as the admin user ?

Try to run slapcat | grep -C5 "dn: cn=admin"

You should get a cn=admin,dc=yunohost,dc=org and a cn=admin,ou=sudo,dc=yunohost,dc=org entries.

(On my server: )

Then, check that the debian package is installed:

# dpkg -l | grep libpam-ldapd      
ii  libpam-ldapd:amd64               0.8.10-4                      amd64        PAM module for using LDAP as an authentication service

Tell me if one of those things is missing.

Ok, so the package was not installed.
So I installed it

apt-get install libpam-ldapd

My postinst configuration of pam was KO, so I launched it again


Then everything was checked

No error anymore in logs about the user admin, can chown admin:admin too. Still need a last restart of yunohost-api

service yunohost-api restart

And it’s back

Ok, it looks like everything is working, including installation of transmission for example.
But this time, I try the unofficial piwik, and again an error about password for admin empty appears. I cannot see in this specific app where it’s coming from it. Will see tomorrow.

There is no reference to the admin UNIX user in the Piwik install script:

But you have to choose one of your YunoHost’s user to appear as the Piwik admin. Maybe you did that wrong ?

Yes, I know, this app is not doing anything with admin user.

In fact, after some reboot/yunohost-api restart/pam reconfiguration with the command upper, it has accepted this time the installation of piwik (by the way, seems initialisation is not properly working, will ask the maintener)

After that I can install strut too. But when I install jirafeau, it fails again, complaining about admin user again.
And yes, the chown command is not working. I don’t understand how it can goes back to the “not working” situation. So I restart service, reconfigure pam, purge libpam-ldapd … and it’s working again. Until few commands and stop working again …

I’m lost on this, no logs on syslog, messages, slapd, yunohost
