In IPA framework we don't properly convert to Python bool type and just
return a string (TRUE or FALSE). This can be seen with many boolean
attributes, like
Bool('idnsallowdynupdate?',
cli_name='dynamic_update',
label=_('Dynamic update'),
doc=_('Allow dynamic updates.'),
attribute=True,
default=False,
autofill=True
),
in 'ipa dnszone-show':
> > > api.Command.dnszone_show('ipa.test')['result']['idnsallowdynupdate']
['TRUE']
This is because we don't have the reverse (from LDAP to Python) mapping
for the LDAP boolean OID 1.3.6.1.4.1.1466.115.121.1.7.
When Web UI asks for the entry, it gets back JSON output that contains
this 'TRUE' value:
"idnsallowdynupdate": [
"TRUE"
],
Add proper mapping from LDAP to Python bool type. With this, a simple
'checkbox' type can be used in Web UI instead of a complex radio-box
setup.
Note that when IPA API is asked to return raw values, 'TRUE' and 'FALSE'
still returned. These are the actual LDAP boolean attribute values. Care
needs to be done in tests:
- if output is from a command with --raw option, 'TRUE' or 'FALSE'
should be expected
- if output if from a normal (non-raw) command, True or False would be
returned

|

There are many structured DNS RR types where DNS data stored in LDAP server
|
|
is not just a scalar value, for example an IP address or a domain name, but
|
|
a data structure which may be often complex. A good example is a LOC record
|
|
[RFC1876] which consists of many mandatory and optional parts (degrees,

|
minutes, seconds of latitude and longitude, altitude or precision).

|
|
It may be difficult to manipulate such DNS records without making a mistake
|
|
and entering an invalid value. DNS module provides an abstraction over these
|
|
raw records and allows to manipulate each RR type with specific options. For
|
|
each supported RR type, DNS module provides a standard option to manipulate
|
|
a raw records with format --<rrtype>-rec, e.g. --mx-rec, and special options

for every part of the RR structure with format --<rrtype>-<partname>, e.g.

--mx-preference and --mx-exchanger.

When adding a record, either RR specific options or standard option for a raw

|
|
one part of a DNS record, where the standard option for raw value is used
|
|
to specify the modified value. The following example demonstrates
|

a modification of MX record preference from 0 to 1 in a record without
