I am looking for password reset portal where users can reset their credentials.  We already have a legacy app written in php but it needs to be retired.

I came across PWM which lists a number of schema changes that are required before it can work with openldap.

I have a few questions:

1) Has anyone used PWM and if so can you describe how stable it operates?  I find the documentation lacking though it seems there's not a ton of issues on their Github site.

2) Has anyone found other solutions besides PWM that do the same thing?
