cfengine, json and quotes

[Berthold Cogel]

Hello,

I'm struggeling with the usage of quotes in JSON.

I want to generate ACLs for OpenLDAP from JSON Files with a mustache
template. So far, everything seemed to work.

{
"access": [
{
"comment": [ "any comment", "with second line"],
"object": "dn.subtree='ou=People,dc=example,dc=com'",
"attrs": "entry,objectclass,uid,cn",
"acl": [ "peername.ip=xxx.yyy.zzz.sss%255.255.255.128 break",
"peername.ip=aaa.bbb.ccc.ttt%255.255.255.128 break" ]
},
{
"comment": [ "next entry", "" ],
"object": "dn.subtree='ou=People,dc=example,dc=com'",
"attrs": "entry,objectclass,uid,cn",
"acl": [
"dn.regex='^cn=([^,]+),ou=AuthConsumer,dc=example,dc=com$' read",
"* break" ]
}
]
}

Reading the data...

"acl_data" data => '{"access": []}';
acl_data" data => data_expand(
readjson("$(constants.conf_dir)/$(this.bundle)/json_data/$(ldap_acl_json)")
),
if =>
fileexists("$(constants.conf_dir)/$(this.bundle)/json_data/$(ldap_acl_json)");


and expanding the mustache works fine.

# any comment
# with second line
access to dn.subtree='ou=ou=People,dc=example,dc=com'
attrs=entry,objectclass,uid,cn
by peername.ip=xxx.yyy.zzz.sss%255.255.255.128 break
by peername.ip=aaa.bbb.ccc.ttt%255.255.255.128 break

# next entry
#
access to dn.subtree='ou=ou=People,dc=example,dc=com'
attrs=entry,objectclass,uid,cn
by dn.regex='^cn=([^,]+),ou=AuthConsumer,dc=example,dc=com$' read
by * break

But this doesn't work with slapd. I have to use double quotes within the
value of an JSON attribute because the slapd accepts only these.


Using something like

"object": "dn.subtree=\"ou=People,dc=example,dc=com\"",

produces

dn.subtree="ou=People,dc=example,dc=com"


Even using double or triple '\' doesn't give anything of use.
Of course I can change JSON and mustache to avoid the quotes within
values, but I like to understand, how to handle this problem the
cfengine way.

Hi Berthold,

Try using {{{x}}} in your mustache template instead of {{x}} around variables.

See Stack Overflow question Mustache: Globally disable html escaping? 

Best,

Aleksey
