Re: EGD not used?

[Steve Romero <sromero@smc.sns.slb.com>]

OpenLDAP users,

I'm having a problem getting the TLS_RANDFILE directive to work (described 
in previous email below), unless I'm not using it right.  The manpage on 
ldap.conf specifies that it is used by ldap clients:

DESCRIPTION
     The ldap.conf configuration file is used to set  system-wide
     defaults  to  be  applied when running ldap clients.  If the
     environment variable LDAPNOINIT is defined,  all  defaulting
     is disabled.

However after configuring TLS_RANDFILE=/var/run/egd-pool (using PRNGD 
here), I'm still receiving the following error when trying to intialize an 
SSL connection to my ldap server:

bash-2.03# /usr/local/bin/ldapsearch -H ldaps://ldap.slb.com -b o=slb,c=an 
alias=sromero dn
ldap_bind: Can't contact LDAP server
        additional info: error:24064064:random number 
generator:SSLEAY_RAND_BYTES:PRNG not seeded

Any ideas on the usage of this directive?

Thanks.

Regards,
Steve Romero

OpenLDAP 2.0 can be configured to use an EGD or an arbitrary
file containing random bits via the ldap.conf TLS_RANDFILE
directive.
