Hi,
Sure, I can file an issue on Jira. As for now, we do get the dates
synchronized in the correct manner from the right source.
Don't mind, I went ahead and created
https://issues.apache.org/jira/browse/SYNCOPE-1070
Regards.
I was reading about the DB connector and I was sure that it stated
that it supported delete as optional:
Authenticate (*/Optional/*) Specify the password column configuration
property.
·Create
·Delete
·Update
·Search
·Schema
·Test
·Sync (*/Optional/*) Specify the Change Log Column configuration property.
I thought that optional was a notation for the fact that it could be
implemented by having the change log column associated with the
resource. I’ll look more into the groovy-scripts. We have had some
parsing problems with those, but that might be due to some file
encoding issue. Therefore we collected the base master data together
from various sources and thought of following the “keep it simple
stupid” policy with the db-connector…J

Hi,
We have now implemented a pullaction, that is able to
automatically generate usernames and passwords from a mssql
database source, that is simulating our HR-system. So far so good.
Cool.
I can also see, that syncope is able to fetch start and end dates
automatically from the db-source(date stated as datetime column),
but, when we try to sync it the other way, we get an exception:
09:40:52.331 ERROR Error parsing value {0} of attribute
Slutdatum:93 Method: handleAttribute
java.lang.NullPointerException: null
*First question:*
Is it now so, that syncope is able to transform and understand a
datetime format quite easily into a correct java.date format when
it pulls this information from an external source, but the
conversion the other way round is troublesome when
pushing/propagating data towards the external resource? Do I need
to transform it first before the propagation? Maybe a SimpleDate
formatter?
When Syncope fetches data from the db-source, we are doing pull.
Consider that such data is arriving in a format according to ConnId
specifications; FYI, ConnId supports the following types:
https://github.com/Tirasa/ConnId/blob/connid-1.4.2.0/java/connector-framework/src/main/java/org/identityconnectors/framework/common/FrameworkUtil.java#L191-L212
where, as you can see, there is no Date.
This means that the date values arrive as text, and are parsed by
Syncope according to the format specified for the mapped internal schema.
At the moment, however, during propagation the eventual conversion
pattern is simply not taken into account:
https://github.com/apache/syncope/blob/2_0_X/core/provisioning-java/src/main/java/org/apache/syncope/core/provisioning/java/MappingManagerImpl.java#L257-L263
There should be room for an improvement here: would you mind to file
an issue on JIRA about propagating Date values as formatted strings?
In that sense, it is better that it fails the other way around,
because we are to fetch the values from the HR and they should not
be managed from the syncope environment.
If such values are not to be used anywhere else in Syncope, then
simply define the internal schema as String rather than Date.
*Second question:*
When a connector has the SEARCH and SYNC operations associated
with itself: how is the logic supposed to work if you do have the
change log column set and deletes a tuple in the external
database? Pull mode is set to incremental. On our end here, even
though we delete the tuple in the mssql hr simulation database,
the associated account is not deleted within syncope. Not even
with pull mode set to “Full reconciliation” funny enough.
What I can see, the pull action handler is not logging anything if
the pull mode is not set to full reconciliation either. Syncope
and the db do have the associated key values set correctly etc.
The change log column is of a datetime format also. Does this has
something to do with it?
You need to consider that everything related to SYNC mostly depends on
how the actual connector implements such operation.
The db-table connector is possibly one of the simplest out there;
among its limitation, it is also not capable to feed Syncope with
information about deleted users.
I would suggest to use the more flexible Scripted SQL for the job;
you'll need, however, to provide your own Groovy scripts.
You might want to look at
https://github.com/apache/syncope/tree/2_0_X/fit/core-reference/src/test/resources/scriptedsql
as starting point; FYI, look how one of such sample scripts can
generate DELETE events to send back to Syncope:
https://github.com/apache/syncope/blob/2_0_X/fit/core-reference/src/test/resources/scriptedsql/SyncScript.groovy#L78
by simply considering an additional 'deleted' column.
