Development in Alfresco

[ganesh]

Hi!

Alfresco is simply the best content management system.Great work!

I want to change some (images)'gifs' and replace them with some other images how can i do that.I had successfully installed your alfresco in my machine.And one more thing is that i have to give access to only some of myfriends( i mean to say i have to filter some users based on their email ids), how can i do that.please help me,where to change the code.
Thanks in advance!

Thanks for your kind comments

The images are unpacked from the WAR at deploy time e.g. for example:

jakarta-tomcat-5.5.12\webapps\alfresco\images
and this folder has the CSS:
jakarta-tomcat-5.5.12\webapps\alfresco\css

You may want to unpack the whole "alfresco.war" file yourself and repack it and redeploy with your changes - otherwise if you redeploy Alfresco you will lose your changes to the images.

You can use the "Manage Space Users" dialog to invite users into specific spaces (effectively controlling their permissions). As the admin user, you can create spaces that are private or only allow the specifically invited users to view or edit documents within them. The "Alfresco Tutorial.pdf" provided with the produce (and installed as part of the bootstrap data) has examples of this.

Thanks!

Kevin

Hi

This code qutoed is a simple example of implementing your own authentication module.

There is quite a bit more to getting LDAP to work.

LDAP support is available in the enterprise product

- Automated group and user import
- LDAP and JAAS based authentication - including Kerberos against ActiveDirectory
- How to configure LDAP with ActiveDirectory and OpenLDAP

Regards

Andy

Where can I find the information you mention about LDAP in Enterprise version?

Thanks
