Sudo and Ldap

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have a quick work around currently, what you can do is create a local
group and add ldap user to the local group. Sudo will accept the group
including users.

sudo will also accept a list of users from ldap, it just doesnt acknowledge
members for groups in FDS?
