LiveCycle ReaderExtensions: “Error 473: Credential permissions are invalid”

Issue

 If you are trying to ReaderExtend a PDF in LCRE 7 either in the web interface, or using the API, you may receive the following error:

Error 473: Credential permissions are invalid...

Reason

 This error is related to the credential permissions provided with LCRE.  There is a .pfx credential file which must be configured with LCRE to allow you to ReaderExtend documents.  This credential is essentially used to certify the PDF when applying the rights, to prevent unauthorized changes to the PDF once distributed.  You need to provide an alias/password for this credential file when installing LCRE.

Often the wrong alias/password combination is used for this credential when installing LCRE.

Solution

 Make sure you use the alias/password provided with the credential file.

Other possible causes:

1) using the wrong JDK or using JDK 1.4.2_10 which is not supported

2) ares-roles.properties, ares-users.properties not correctly mapping users in

C:\Program Files\Adobe\LiveCycle\ReaderExtensions\jboss-3.2.5\server\all\conf

LiveCycle PDFG: file bloat when converting PDF to PDFA

Issue

 When converting a PDF to PDF/a you may notice that the file size becomes bloated, for example 18KB -> 448KB.

Reason

 There are 2 reasons for the increase in size when we select the “PDFA-1b” conversion:

1) extra fonts which get embedded in the resulting PDF/a document

2) the color scheme chosen in the “PDFA-1b” setting. If you select CMYK then the size gets increased drastically. But if you choose RGB then the difference in size is negligible, assuming there are no fonts to be embedded.

Solution

 To get the smallest file-size during PDF to PDF/a conversion, you should use the RGB conversion options.
