QuickBuild's administrator currently can't add user from LDAP and make use of LDAP groups used inside company.
Two improvments:
1) QuickBuild's administrator can add user passing only their login name - QuickBuild will add this user getting data from LDAP in the same way how do this when user logging to QB.
2) Integration with LDAP groups. Proposition of implementation: each QuickBuild group will have optional field "LDAP filter". If new LDAP user pass this filter (belong to such group or etc...) their automatically become the member of this QuickBuild group.

Thank You in advanced,

Jan
