@angryhippy said in Cannot Log In To Web Admin panel:

[ERROR] (api) LDAP: Bind failed for dn=uid=kolab-service,ou=Special Users,dc=jonras,dc=home. Invalid Credentials

See your /etc/kolab/kolab.conf, there are service_bind_dn and service_bind_pw in the [ldap] section.

Did you modify something there?

Perhaps you need to do a full clean install again?
