ldap_search_s(...) fail sometimes; LdapErr: "...successful bind must be completed..."   

Hi,

I have a question relating to ldap_search_s.

Before I call the ldap_search_s function, I do following steps:

1.	ldap_initialize(&pldap, hostname);
2.	ldap_set_option(.);
3.	ldap_bind_s(pldap, NULL, NULL, LDAP_AUTH_SIMPLE);

Then I call the function:
ldap_search_s(pldap,base,LDAP_SCOPE_SUBTREE,filter,attrs,0,&result);


My simple program works in a strange way:
Sometimes the ldap_search_s functions works and receives the wanted
information.
But after a few runs, the same code fails and returns "operations
error":

I call the function "ldap_get_option(pldap,LDAP_OPT_ERROR_STRING,&errorstring)"
to get more informations. It receives following string

"00000000: LdapErr: DSID-0C0905FF, comment: In order to perform this
operation a successful bind must be completed on the connection., data
0, vece"

Why does it sometimes work/not work? What can I do that my program
runs without this strange habit?

Regards,
berni
