This allows for a consistent way to retrieve the value from LDAP. The method is used to find an existing entry. It is not usable to add or remove entries. Moving it in the code allows the value to always be set in the substitution dictionary and not rely on a specific caller. It was moved to installutils.py to avoid circular import. https://pagure.io/freeipa/issue/8885 Signed-off-by: Rob Crittenden <rcritten@redhat.com> Reviewed-By: Florence Blanc-Renaud <flo@redhat.com> Reviewed-By: Alexander Bokovoy <abokovoy@redhat.com> Reviewed-By: Florence Blanc-Renaud <flo@redhat.com> Reviewed-By: Alexander Bokovoy <abokovoy@redhat.com>

-----------------------
|
|
|
|
dn_by_rdn_count = {
|
|
3: 'cn=config,dc=example,dc=com':
|
|
4: 'cn=bob,ou=people,dc=example,dc=com',
|
|
}
|
|
|
|
all_updates = [
|
|
{
|
|
'dn': 'cn=config,dc=example,dc=com',
|
|
'default': [
|
|
dict(attr='attr1', value='default1'),
|
|
],
|
|
'updates': [
|
|
dict(action='action', attr='attr1', value='value1'),
|
|
dict(action='replace', attr='attr2', value=['old', 'new']),
|
|
]
|
|
},
|
|
{
|
|
'dn': 'cn=bob,ou=people,dc=example,dc=com',
|
|
'default': [
|
|
dict(attr='attr3', value='default3'),
|
|
],
|
|
'updates': [
|
|
dict(action='action', attr='attr3', value='value3'),
|
|
dict(action='action', attr='attr4', value='value4'),
|
|
}
|
|
}
|
|
]
|
|
|
|
Please notice the replace action requires two values in list
|
|
|
|
The default and update lists are "dispositions"
|
|
|
|
Plugins:
|
|
|
|
Plugins has to be specified in update file to be executed, using
|
|
'plugin' directive
|
|
|
|
Example:
|
|
plugin: update_uniqueness_plugins_to_new_syntax
|
|
|
|
Each plugin returns two values:
|
|
|
|
1. restart: dirsrv will be restarted AFTER this update is
|
|
applied.
|
|
2. updates: A list of updates to be applied.
|
|
|
|
The value of an update is a dictionary with the following possible
|
|
values:
|
|
- dn: DN, equal to the dn attribute
|
|
- updates: list of updates against the dn
|
|
- default: list of the default entry to be added if it doesn't
|
|
exist
|
|
- deleteentry: list of dn's to be deleted (typically single dn)
|
|
|
|
For example, this update file:
|
|
|
|
dn: cn=global_policy,cn=$REALM,cn=kerberos,$SUFFIX
|
|
replace:krbPwdLockoutDuration:10::600
|
|
replace: krbPwdMaxFailure:3::6
|
|
|
|
Generates this list which contain the update dictionary:
|
|
|
|
[
|
|
{
|
|
'dn': 'cn=global_policy,cn=EXAMPLE.COM,cn=kerberos,dc=example,dc=com',
|
|
'updates': [
|
|
dict(action='replace', attr='krbPwdLockoutDuration',
|
|
value=['10','600']),
|
|
dict(action='replace', attr='krbPwdMaxFailure',
|
|
value=['3','6']),
|
|
]
|
|
}
|
|
]
|
|
|
|
Here is another example showing how a default entry is configured:
|
|
|
|
dn: cn=Managed Entries,cn=etc,$SUFFIX
|
|
default: objectClass: nsContainer
|
|
default: objectClass: top
|
|
default: cn: Managed Entries
|
|
|
|
This generates:
|
|
|
|
[
|
|
{
|
|
'dn': 'cn=Managed Entries,cn=etc,dc=example,dc=com',
|
|
'default': [
|
|
dict(attr='objectClass', value='nsContainer'),
|
|
dict(attr='objectClass', value='top'),
|
|
dict(attr='cn', value='Managed Entries'),
|
|
]
|
|
}
|
|
]
|
|
|
|
Note that the variable substitution in both examples has been completed.
|
|
|
|
Either may make changes directly in LDAP or can return updates in
|
|
update format.
