Lists: | pgadmin-support |
So after installing pgadmin4 from .deb-file and trying out several
configurations, i found out a working one, but with a
file-permission-issue. Because i didn't try out which specific file made
the problems, i chown-ed all pgadmin4/web/*-files to www:data:www-data,
since pgadmin4 from the .deb-file is hosted by apache2. So finally i got
it working.
After that i adapted my docker-parameters to
> docker run -p 8280:80
-e "PGADMIN_DEFAULT_EMAIL=<emaiAddress>"
-e "PGADMIN_DEFAULT_PASSWORD=<password>"
-e "PGADMIN_CONFIG_AUTHENTICATION_SOURCES=['ldap']"
-e "PGADMIN_CONFIG_LDAP_AUTO_CREATE_USER=True"
-e "PGADMIN_CONFIG_LDAP_SERVER_URI='ldaps://dc.mydomain.local:636'"
-e "PGADMIN_CONFIG_LDAP_BASE_DN='cn=Users,dc=mydomain,dc=local'"
-e "PGADMIN_CONFIG_LDAP_USE_STARTTLS=True"
-e
"PGADMIN_CONFIG_LDAP_BIND_USER='cn=user,cn=Users,dc=mydomain,dc=local'"
-e "PGADMIN_CONFIG_LDAP_BIND_PASSWORD='<bind-password>'"
-e "PGADMIN_CONFIG_LDAP_CA_CERT_FILE='/certs/ca.crt'"
-e "PGADMIN_CONFIG_LDAP_CERT_FILE='/certs/client.crt'"
-e "PGADMIN_CONFIG_LDAP_KEY_FILE='/private/client.key'"
-e "PGADMIN_CONFIG_LDAP_USERNAME_ATTRIBUTE='sAMAccountName'"
-e
"PGADMIN_CONFIG_LDAP_SEARCH_BASE_DN='cn=Users,dc=mydomain,dc=local'"
-v '/local/path/to/ca.crt:/certs/ca.crt'
-v '/local/path/to/client.crt:/certs/client.crt'
-v '/local/path/to/client.key:/private/client.key'
-d <my docker-image>
As expected, i got the same file-permission-issue. So i interactively
entered the docker-session with
> docker exec -it -u 0 <container id> /bin/sh
and did
> chown -R pgadmin:pgadmin /pgadmin4/*
since the process is running under user pgadmin and
> chmod 644 /private/*
> chmod 644 /certs/*
as a quickfix. So i finally got it working, so that i can login with a
valid sAMAccountName and password. It would be great if you would fix
that file-permission-issues in the image as well as in the .deb-file.
Due to the issue, i got
LDAPSocketOpenError socket ssl wrapping error: [Errno 13] Permission denied
before.
