generate JWT token from LDAP auth

Hi all,

I have a requirement like elaborated below - 

Two Applications are there,

1- Appian application which is authenticating through LDAP

2. Another app built using spring boot authenticating through LDAP only and generating token

Note:  both are using same credentials to login means same LDAP is configured at both places 

requirement is supposed someone logged in through Appian application, we can provide link to access to 2nd application and need to pass token from Appian.

how can we generate token from appian by LDAP login?

Thanks in Advance.
