If you are trying to decide between this and the MySQL version, this is better.
I've tried to document what I learned setting up pwm-1.8.0-SNAPSHOT-2016-10-26T09:44:11Z-pwm-bundle.zip from https://github.com/pwm-project/pwm, an LDAP self-service java webapp on Oracle Linux 6.  RHEL or CentOS should work exactly the same.
My lastest attempt as of 2/22/17, worked on Oracle Linux 7 (should work exatly the same on CentOS 7 or RHEL 7) _updating to_ the file pwm-1.8.0-SNAPSHOT-2017-02-19T20:34:49Z-pwm-bundle.zip from https://github.com/pwm-project/pwm

For the impatient:
DONT RUN TOMCAT UNMODIFIED on your FreeIPA server.  FreeIPA uses its own Tomcat.
Install java 7, tomcat 7 from binaries at the Apache website (don't use distro's packages), and deploy the pwm.war file.
Adjust your firewall to open TCP 8080, if using default Tomcat settings.
The guided configuration wizard doesn't work because you have to adjust the unique ID attribute name, use manual configuration.
Choose OpenLDAP for the configuration type.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
