I m trying to integrate ldap with devstack and when i did ./stack.sh i got this localrc: line 9: KEYSTONE_IDENTITY_BACKEND: command not found - ldap

Question

localrc file
ADMIN_PASSWORD=password2 MYSQL_PASSWORD=password2
RABBIT_PASSWORD=password2 SERVICE_PASSWORD=password2
SERVICE_TOKEN=token2
ENABLED_SERVICES=key,n-api,n-crt,n-obj,n-cpu,n-net,n-cond,cinder,c-sch,c-api,c-vol,n-sch,n-novnc,n-xvnc,n-cauth,horizon,mysql,rabbit,ldap
KEYSTONE_IDENTITY_BACKEND=ldap
KEYSTONE_CLEAR_LDAP=yes LDAP_PASSWORD=9632
I followed this website(http://www.ibm.com/developerworks/cloud/library/cl-ldap-keystone/)

Answer 1

I am assuming the above snippet is from a file written in shell script. Your example looks Ok.
I checked the link you provided and noted that the line you say failed is written in the IBM example as:
KEYSTONE_IDENTITY_BACKEND = ldap
Which is not legal sh (or bash) and would cause the error message you described.
KEYSTONE_IDENTITY_BACKEND = ldap
-bash: KEYSTONE_IDENTITY_BACKEND: command not found
I suspect you copied and pasted the bad example from the link into your localrc file, which caused the error you saw, but somehow when you wrote the SO question, you corrected the mistake by removing the spaces around the "=".
Edit: Investigation
;TLDR
Create a file in the root of the devstack repo, devstack/local.conf with the contents:
[[local|localrc]]
ADMIN_PASSWORD=password2
MYSQL_PASSWORD=password2
RABBIT_PASSWORD=password2
SERVICE_PASSWORD=password2
SERVICE_TOKEN=token2
ENABLED_SERVICES=key,n-api,n-crt,n-obj,n-cpu,n-net,n-cond,cinder,c-sch,c-api,c-vol,n-sch,n-novnc,n-xvnc,n-cauth,horizon,mysql,rabbit,ldap
KEYSTONE_IDENTITY_BACKEND=ldap
KEYSTONE_CLEAR_LDAP=yes
LDAP_PASSWORD=9632
Full Description
I installed devstack on Centos7 (using the Devstack Quick Start Guide):
git clone https://git.openstack.org/openstack-dev/devstack
cd devstack
./stack.sh
I entered passwords as prompted, but eventually it failed with the error:
Error: pg_config executable not found.
Please add the directory containing pg_config to the PATH
or specify the full executable path with the option:
python setup.py build_ext --pg-config /path/to/pg_config build ...
or with the pg_config option in 'setup.cfg'.
I traced the problem to a limited PATH in the sudoers entry, and because my postgreSQL install is in a non-standard location, I linked pg_config into /usr/local/bin and ran stack.sh again:
sudo ln -s /usr/pgsql-9.3/bin/pg_config /usr/local/bin/pg_config
./stack.sh
(You probably won't have to do this if Postgres is in a standard location).
Install took a long time -

I killed the devstack session and did it all again with a clean git repo and with a localrc file.
./unstack.sh
cd ..
git clone https://git.openstack.org/openstack-dev/devstack
cd devstack
cat << __EOF > local.conf
[[local|localrc]]
ADMIN_PASSWORD=password2
MYSQL_PASSWORD=password2
RABBIT_PASSWORD=password2
SERVICE_PASSWORD=password2
SERVICE_TOKEN=token2
ENABLED_SERVICES=key,n-api,n-crt,n-obj,n-cpu,n-net,n-cond,cinder,c-sch,c-api,c-vol,n-sch,n-novnc,n-xvnc,n-cauth,horizon,mysql,rabbit,ldap
KEYSTONE_IDENTITY_BACKEND=ldap
KEYSTONE_CLEAR_LDAP=yes
LDAP_PASSWORD=9632
__EOF
./stack.sh
This time there were no password prompts, so the local config was definitely read.
