I am using the fabric-network module to connect to the the certificate authority to enroll the admin and the user. But I wanted to have custom affiliation so i made changes in the fabric-ca-server-config.yaml and fed it to the ca container by using volumes. But after doing that i am getting this error:
Error: fabric-ca request enroll failed with errors [[ { code: 20, message: ‘Authentication failure’ } ]]

when trying to enroll admin or any user(you can’t without an admin).

The same thing is working if i dont feed the edited fabric-ca-server-config.yaml to the container, it creates the default affiliations which does not give any authentication errors.

This is my connection-profile.json

}

the tlsCACerts are copied from crypto-config/peerOrganizations/police.evidence-vault.com/tlsca/tlsca.police.evidence-vault.com-cert.pem

the tls ca pem files are the same for all the peers in that organizations are the same, so i pasted the the pem everywhere in the connection profile

After encountering this error:

I took a look at the volumes of the CA and found there were two files ca.crt and tls-cert.pem files in the volume.
Tried both of them either placing them here:

"certificateAuthorities": {
        "ca.police.evidence-vault.com": {
            "url": "https://localhost:7054",
            "caName": "ca.police.evidence-vault.com",
            "tlsCACerts": {
                "pem": ....
            },
            "httpOptions": {
                "verify": false
            }
        }
    }

in the connection profile.
or
at every place in the connection profile which needed a pem.

but still got the same error:
Error: fabric-ca request enroll failed with errors [[ { code: 20, message: ‘Authentication failure’ } ]]
