Re: Help with authz-regexp mapping kerberos identity to dn ....SASL

Hi Chavez,
This is the authz-regexp string I have used in slapd.conf:

authz-regexp uid=([^,]*),cn=synovel.com,cn=gssapi,cn=auth uid=$1,ou=People,dc=synovel,dc=com

This works if the SASL auth mechanism is gssapi. I have also hard-coded the SASL Realm with the below config option:

sasl-realm SYNOVEL.COM

If it uses the default realm (i.e. sasl-realm option is missing) then the string would probably be:

authz-regexp uid=([^,]*),cn=gssapi,cn=auth uid=$1,ou=People,dc=synovel,dc=com

Hope this is of some assistance. For furthur information, kindly read http://www.openldap.org/doc/admin24/sasl.html#Mapping%20Authentication%20Identities .

Hello all,
My plan is to use Kerberos and LDAP as a replacement for NIS.
My issue is that I need my kerberos credentials to map to a user in LDAP
so I can avoid permission issues when logging in with kerberos creds.
All the perms are based on the UNIX/LDAP users and groups. Thing is the
user id's are different between kerberos and LDAP.
The kerberos names consist of firstname_lastname@REALM. The ldap entries
are in the format of standard Unix user names or first letter of first
name and up to 7 characters of the last name (jmontana). I migrated the
LDAP entries from my existing NIS maps.
Now I understand that I can use SASL and authz-regexp in slapd.conf to
map these id's. Please correct me if I am wrong.

I added all the corresponding  "krbName: first_last@REALM" to the users
when I added them to the LDAP directory.
For example for user Joe Montana..His ldap dn is "dn:
His uid is "uid: jmontana
And his Krb name is ""krbName: joe_montana@TEST.EXAMPLE.COM"

I think all the data is there to get a mapping I just am unsure of the
auth-regexp strings I need to add to the slapd.conf file.
Does anyone out there have any experience with this and better yet
provide the string or example of what strings I can use?
I have searched the net on how to authenticate with kerberos and
effictively login with a local id but have been unsuccessful in my
Appreciate any help.

Thank You
