Error message - invalid credentials on Piwik 2.14

My client sent me an image of error message below and I have no idea on how to resolve.

WARNING: /var/www/html/piwik/plugins/LdapLogin/Ldap/Client.php(132) Warning - ldap_bind() - Unable to bind to server; invalid credentials - Piwik 2.14, please report this message in the Piwik forums: http://forum.piwik.org (please do a search first as it might have been reported already)

I can tell you that the server is working fine and LDAP is in working order. Could it be the PC that my client used?

Much appreciated,

djh

Hi there, maybe ask this in the LDAP plugin issue tracker? Issues · matomo-org/plugin-LoginLdap · GitHub
