LDAP passport strategy for Hyperledegr composer - github

Question

I have been trying to use LDAP passport strategy for authentication in hyperledger composer rest server. I am using below configuration for ldap passport:
export COMPOSER_PROVIDERS='{
"ldap": {
"provider":"ldap",
"authScheme":"ldap",
"module":"passport-ldapauth",
"authPath":"/auth/ldap",
"successRedirect":"/",
"failureRedirect":"/",
"server":"{
"url":"ldap://localhost:389",
"bindOn":"cn=admin,dc=example, dc=com",
"bindCredentials":"*****",
"searchBase":"ou=admin,dc=example,dc=com",
}"
}
}'
While starting composer-rest-server with authentication its showing error
SyntaxError: Unexpected token
in JSON at position 210
at JSON.parse (<anonymous>)
at Promise.then (/home/mfgteg/.nvm/versions/node/v8.9.3/lib/node_modules/composer-rest-server/server/server.js:127:34)

Answer 1

I got the correct format. Thanks to a link I found on IBM site
I used the following configuration :
export COMPOSER_PROVIDERS='{
"ldap": {
"provider": "ldap",
"authScheme": "ldap",
"module": "passport-ldapauth",
"authPath": "/auth/ldap",
"successRedirect": "/",
"failureRedirect": "/",
"server": {
"url": "ldap://localhost:389",
"bindDn": "cn=admin,dc=example, dc=com",
"bindCredentials": "*****",
"searchBase": "ou=admin,dc=example,dc=com"
}
}
}'
However I am yet to figure out what to mention in "callbackURL".

Use the variable provided below. Just change the successRedirect and credentials as per your configuration. Also in case you are running Client application on some other machine, you may need to change the localhost in url to your machine IP address.
Note : I have tested this with open LDAP configured.
COMPOSER_PROVIDERS='{
"ldap": {
"provider": "ldap",
"authScheme": "ldap",
"module": "passport-ldapauth",
"authPath": "/auth/ldap",
"successRedirect": "Where you want to redirect",
"failureRedirect": "/ldap",
"session": true,
"json": true,
"LdapAttributeForLogin": "cn",
"LdapAttributeForUsername": "cn",
"server": {
"url": "ldap://localhost:389",
"bindDN": "cn=admin,dc=hsc,dc=com",
"bindCredentials": "xxxxx",
"searchBase": "ou=users,dc=hsc,dc=com",
"searchFilter": "(cn={{username}})"
}
}
}'
