Configured LDAP and login stuck at "Verifying" -- how to disable GRAVATAR for LDAP authentication?

[JSOLERP]

Hello,

We just set up LDAP and when trying to log in, I see it is stuck in “Verifying…” when trying to “log in with LDAP”

We operate in secured/firedwalled environment, so I am used to checking firewall during issues like this. I notice that the ERPNEXT server is trying to contact 192.0.73.2:443 while we try to log in.

any suggestions would be appreciated. Thanks!

UPDATE: SEE BELOW. This appears to be caused by a check to gravatar.com being required in order to let the LDAP user log in.

Kept digging… looks like it’s GRAVATAR

So if you don’t allow ERPNEXT server to reach gravatar, you can not log in with LDAP.

Also FYI here:

Running Frappe/ERPNext locally; no external network access

Is there a defined method for running Frappe in an isolated network without access to the internet? I mean disabling the use of external dependencies like google fonts, gravatar, etc. To be clear, I do not mean the situation like this. The question there seemed to be more about batching transactions remotely during periods of downtime between client/server. I need to know if Frappe/ERPNext can gracefully run 100% local.

So I think this is “solved” in the sense that we know what is causing it, but not solved because we don’t know how to disable GRAVATAR for LDAP authentication.

for now I resolved problem with this fix:
