Hi,

I'm running FreeIPA 3.0 under RHEL6.4. I'm seeing some unexpected behaviour with winsync replication.

1. I have a working winsync agreement, and users are synced correctly.

2. If a user already exists in in IPA when I sync it from AD, I'm seeing the following in the dirsrv error logs:

[25/Nov/2013:14:29:03 +0000] NSMMReplicationPlugin - windows_update_local_entry: failed to modify entry uid=username,cn=users,cn=accounts,dc=domain,dc=net - error 21:Invalid syntax

    I assume this is because the user already exists in dirsrv? Fine.

No. Error 21 is Invalid Syntax. This means the format of the data in the attribute in AD is not correct for the given syntax. For example, if the syntax is Integer, this means the data should be a valid integer. However, AD allows data that violates LDAP syntax.

Can you post the data from the AD entry that corresponds to uid=username,cn=users,cn=accounts,dc=domain,dc=net? Please be sure to obscure any sensitive data. I'd like to identify the data that is causing this problem.

Certainly, here goes:

mobile:: KzQ2NzI3mjMEMTEwwqAJ

I think this may be the problem. mobile contains non printable characters:
$ python
>>> import base64
>>> base64.b64decode('KzQ2NzI3mjMEMTEwwqAJ')
'+46727\x9a3\x04110\xc2\xa0\t'

Looks like the mobile phone number contains utf8 characters.  It must not:
    /* Per RFC4517:
     *
     * TelephoneNumber = PrintableString
     * PrintableString = 1*PrintableCharacter
     */

Unfortunately, AD syntax checking leaves a lot to be desired, so it allows this and other bogus data. IPA/389 is much stricter.
Hey Rich,

You are correct!

All "mobile" entries in our AD is base64 encoded and ends with "\xc2\xa0\t". Removing the junk characters from the mobile entry makes the user sync correctly, regardless of if the user pre exists or not. Issue solved, thanks alot for pointing this out!
