Propagation of environment variable in exec

[MonsieurRz]

Context: multi-provider setup

Hello,
I have one environment variable of the Apache process that is the value of the client_secret.
I have tried getting it through exec in the *.client file but it appears its environment is only constituted of:
PWD=/usr/bin
SHLVL=1
_=/usr/bin/env

Would it be possible to propagate the parent process environment ?

you'll need to use PassEnv see: https://httpd.apache.org/docs/2.4/mod/mod_env.html#passenv

Although I successfully log the PassEnv value in a typical Apache config file. I could never have it through exec (in JSON client file) using PassEnv in any context.
Do you happen to have tried it ?

apparently the environment does not get propagated indeed; since the code is borrowed from AuthLDAPBindPassword you may try an approach similar to https://dba.stackexchange.com/questions/306305/store-ldap-bind-credentials-in-environment-variables-for-pg-hba-conf
