Re: Got error while enabling SASL

Hi All,

I hope now i'm only 1 step far:

I've enabled the ldapdb auxprop plugin.

/u01/app/openldap/product/2.4.26/etc/openldap>pluginviewer -a

Installed auxprop mechanisms are:

ldapdb sasldb

List of auxprop plugins follows

Plugin "ldapdb" ,   API version: 4

       supports store: yes


Plugin "sasldb" ,   API version: 4

       supports store: yes


File modified (newly created): /usr/lib64/sasl2/pluginviewer.conf

Now, its getting me to the different point:
Whatever i'm executing - its getting hanged for infinite time.

ldapsearch -x -D cn=Manager,o=xyz -W -b 'uid=sasluser21,ou=System,o=xyz'
Enter LDAP Password:

So, after taking its passwd ....no result :(

One more thing:
ldapwhoami -Y DIGEST-MD5 -U sasluser21 -H ldap://localhost
SASL/DIGEST-MD5 authentication started

Same result - NO O/P.

Plz help.

Thanks and Regards,
Gaurav Gugnani

Hello All,

i was working on this problem and figured out that ldapdb plugin auxprop is missing.

 Installed SASL (server side) mechanisms are:

I read that to use such thing, ldapdb auxprop plugin should be enabled.

The package has been installed and the below files are there:

Please help me, how to set SASL using ldap directory.

Hello All,

Thks to all for helping me out. i hope now the destination is not too far as i achieved the SASL but it is storing using sasldb.
However, i want it to store information in ldap direcotry.

I've installed the corresponding package:

Steps for SASL in LDAP using sasldb

1> saslpasswd2 -c sasluser14
2> sasldblistusers2

3> service ldap stop

4> vi etc/openldap/slapd.conf
      sasl-auxprops sasldb

      authz-regexp uid=([^,]*),cn=DIGEST-MD5,cn=auth uid=$1,ou=System,o=xyz
      - Give proper ACL to sasluser14
5> cat /usr/lib64/sasl2/slapd.conf
# SASL Configuration
pwcheck_method: auxprop
auxprop_plugin: sasldb
#auxprop_plugin: slapd
sasldb_path: /etc/sasldb2

6> service ldap start

7> ps -eaf | grep -i ldap

8> vi add_sasl_accnt14.ldif

   # TEST Account for SASL:
   dn: uid=sasluser14,ou=System,o=xyz
   uid: sasluser14

   ou: System
   description: Special account for SASL Testing
   userPassword: sasluser14
   objectClass: account
   objectClass: simpleSecurityObject

9> ldapadd -x -D cn=Manager,o=xyz -W -f add_sasl_accnt14.ldif   

10> ldapsearch -Y DIGEST-MD5 -U sasluser14 -b 'uid=sasluser7,ou=system,o=xyz'

But now the problem is - it is storing the users in sasldb. and we want to use ldap directory.
Can any one please suggest - What changes i need to make to achieve it?

Thks a lot for your support.

You should run your server in debug mode to determine what's going awry.


/u01/app/openldap/product/2.4.26/etc/openldap>ldapsearch -Y DIGEST-MD5 -U
sasluser7 -b 'o=xyz'
SASL/DIGEST-MD5 authentication started
Please enter your password:
ldap_sasl_interactive_bind_s: Invalid credentials (49)
      additional info: SASL(-13): user not found: no secret in database

I checked for ACL and also now i'm using authz with following lines:

authz-regexp uid=([^,]*),cn=DIGEST-MD5,cn=auth uid=$1,ou=System,o=xyz

access to attrs="userpassword"
      by self write
      by anonymous auth
      by dn="uid=sasluser7,ou=System,o=xyz" read
access to dn.base="o=xyz"
      by dn="uid=sasluser7,ou=System,o=xyz" read
      by users read
access to dn.subtree="ou=Subscribers,o=xyz"
      by dn="uid=sasluser7,ou=System,o=xyz" read
access to *
      by self write
      by dn="uid=sasluser7,ou=System,o=xyz" read

I hope it is fine.

I have 'by anonymous auth' on the following:

access to dn.base="ou=people,dc=example,dc=net"
access to attrs=userPassword
access to attrs=authzTo
access to attrs=objectClass
access to attrs=entry,uidNumber

You could determine if that's sufficient for you piecemeal wise but, again,
use debug output to figure it out. For example:

slapd -d -1 -h ldap:/// -u openldap -g openldap

See the manpage for slapd for details.

Moreover, we can say that the user is created:
/u01/app/openldap/product/2.4.26/etc/openldap>ldapsearch -x -W -D
'cn=manager,o=xyz' -b 'uid=sasluser7,ou=System,o=xyz'
Enter LDAP Password:
# extended LDIF
# LDAPv3
# base <uid=sasluser7,ou=System,o=xyz> with scope subtree
# filter: (objectclass=*)
# requesting: ALL

# sasluser7, System, xyz
dn: uid=sasluser7,ou=System,o=xyz
uid: sasluser7
ou: System
description: Special account for SASL Testing
userPassword:: c2FzbVHzZXI3

Be aware that the above is a simple uuencoding of your password. It should
now be considered publicly known.

objectClass: account
objectClass: simpleSecurityObject

# search result
search: 2
result: 0 Success

# numResponses: 2
# numEntries: 1

Also, i would like to highlight one thing:

That when i check for sasl dblist users - it thorws me an error. Can that
be an issue point?
-bash: sasldblistusers: command not found

Any of the cyrus sasl* commands are most likely doing the wrong thing,
which default to using the sasldb auxprop store (which uses /etc/sasldb2)
rather that slapd or ldapdb. I would not use them at this point as they're
bound to confuse the matter.
