[opencms-dev] Portal integration (portlet version?)

[David Valls roure]

Hi List,

a customer wants a site based on CMS with some common portal functionalities:
Personal sections; a user managed zone with featured content; LDAP  
integration; document lifecycle workflow; forum, media gallery,  
templates, forms, event calendar, blog and wiki support...

can we do all this job using only OpenCMS (without too much development...) ?
or is a better aproach integrate OpenCMS in a portal environment that  
supplies all major funcionalities (if it is possible...) ?

Thanks in advice,

David.
