Debian package of web2ldap? (I was not aware of one.) I remember the discussion about the first revisions of the Python CNRI license draft. I already thought about this problem concerning web2ldap. Several solutions came to my mind: 1. Rewriting the ASN.1 parser module I already contacted the author of http://pysnmp.sourceforge.net. His package (with VERY liberal license) contains a module ber.py which implements encoding/decoding some basic ASN.1 types needed for SNMP. I pointed him at Pisces a couple of weeks ago and sent him my current version of pisces.asn1. Maybe he's interested in contributing a clean-room implementation. Not sure about how interested Jeremy Hylton is. Technically I like the idea of mapping ASN.1 types to Python objects and I'm currently trying to (hopefully) improve the module in this direction. But currently I do not have much spare time though. Contributions welcome. 2. I thought about relaxing the license of web2ldap. I have to admit that up to now I was too lazy for reading a bunch of licenses to choose "the right one". 3. A short-term solution would be to provide my patched version of pisces.asn1 on a completely separate download page. web2ldap works without it except displaying of X.509 certs/CRLs. The presence of pisces.asn1 is automatically detected anyway => you can make a Debian package without the ASN.1 module and the few users who really need the X.509 stuff can easily download and install pisces.asn1. Note: I'm using a patched version of pisces.asn1. NOT the one from the Pisces distribution. > We would be on the safe side and could distribute web2ldap though, if the > author of web2ldap choose to include an exception clause in his license that > explicitely permits usage of his code with code under this CNRI license. Can you give me an example clause? > Note that all authors of GPL code involved had to agree, though. Puh, I'm only one. So far the good news... ;-) Ciao, Michael.
