Re: How is LDAP used in EPICS installations

["Williams Jr., Ernest L. via Core-talk" <core-talk at aps.anl.gov>]

Hi George,

For SLAC, our authentication stack looks like:

PAM ---> SSSD ---> KERBEROS ---> LDAPS

We are getting very close to Single-Sign-On (SSO)  as well.

We are very interested in pursuing EPICS Security and its integration with our authentication stack.

I am starting to gather some requirements here at SLAC that we will feedback to the team.

More details soon.

Cheers,

Ernest

Subject: How is LDAP used in EPICS installations

 

Hi all

I’m working on the new Secure PVAccess implementation of PVXS, with Micheal and Kay.  We are at a stage where we are testing various authentication methods with the new protocol.  One of those we’re looking at is LDAP.  We want to reach out to the community to determine how you see people actually using LDAP.   Are they using it for login (i.e. providing username and password (that is configured and managed by LDAP) to the LDAP API) and then using success to provide access to resources; are they using Kerberos for user authentication and LDAP primarily for user profile information and groups (e.g. phone, office, group); finally some hybrid PAM, SSSD etc. We want to get an idea of what we should provide as integration.  

One of the questions is how we should use and access LDAP groups when it comes to the upgraded EPICS Security.

Please feel free to reply if you have any experience with how LDAP is used to log in and or to provide group information to be used with or aside from authorization.

Cheers
