Hello Matt Pallissard ,
Have you succeeded in using LDAP as a dynamic back-end for bind 9.11?
We are getting below errors while trying to make bind initialization with dyndb.
loading DynDB instance 'ldap_dyndb' driver '/usr/lib64/libldap.so'
failed to lookup symbol dyndb_version in dyndb module '/usr/lib64/libldap.so': /usr/lib64/libldap.so: undefined symbol: dyndb_version
failed to dynamically load instance 'ldap_dyndb' driver '/usr/lib64/libldap.so': (null) (failure)
dynamic database 'ldap_dyndb' configuration failed: failure
loading configuration: failure
exiting (due to fatal error)
The configuration details related to bind in named.conf file is as below.
dyndb ldap_dyndb "/usr/lib64/libldap.so" {
uri "ldap://10.12.42.113";
base "cn=dns, dc=example, dc=com";
};
We are using bind 9.11 version package in RHEL 7.2 and have few queries as below.
- We used the default RHEL "/usr/lib64/libldap.so" shared library in the above configuration. Is this correct? Is there any customized ldap.so file to be used for bind 9.11.
- Are there any specific configure options to be enabled while compiling bind ?
Any inputs are highly appreciated and Thanks in advance.
Thanks,
Kishore.
