Credential Cache Problem

[Pankaj Mathur]

Hi,

I am using OpenLDAP-2.2.26 with Cyrus SASL-2.1.20.

The problem is that when I use DIGEST-MD5 binding with openldap, for a 
particular user say - 'user1', then the first time it works; then if I use 
'user1' again, it fails and says 'Invalid Credentials'. I checked the userid 
and password, which is being sent correctly.
To get rid of this problem, I have to log in as a second user (say 'user2'), 
and then if I use 'user1' again, it works.
This suggests that some kind of caching is happening at the at SASL level.
How can I turn off this caching?

Please help!!
(Please also see the function calls being made in OpenLDAP below).
Thanks,
P.

I am using ldap_sasl_interactive_bind_s in the following way in a function 
(which consists of just the code below):


void* defaults = NULL;
int rc = 0;
defaults = lutil_sasl_defaults( ld,
(char*)mechanism,
NULL,
(char*) dn,
cred->bv_val,
NULL );


rc= ldap_sasl_interactive_bind_s( ld, (char*) dn, (char*) mechanism, NULL, 
NULL,
LDAP_SASL_AUTOMATIC, lutil_sasl_interact, defaults );

lutil_sasl_freedefs( defaults );

(When using DIGEST-MD5, it works fine for the first time within a process, 
however when calling it again in a separate LDAP connection, it returns 
"Invalid Credentials".)
