How to use environment variable for LDAP bindPW?

[LisaHLi]

I can't find any document tells how to use environment variable.
What I did is adding a system level environment variable 'LISA'.
In config yaml I tried to use it for issuer (the target is to set it for bindPW)
issuer: $LISA
or
issuer: '$LISA'
or
issuer: {{ .Env.LISA}}

None of them works. I'm using v2.39.0, not using docker but installed it as a windows service.

Figured out how - pretty straight forward, just use
"$LISA"

But seems it can't be applied everywhere.
It'll be better if we have a document to tell where env variables can be used. (#2022 (reply in thread) says it only works for connectors and storage)

But https://github.com/dexidp/dex/blob/master/config.docker.yaml shows another way to use variables.

Moreover, for static password, hashFromEnv attribute should be used instead (#1099)
