Hyperlink to other mobile application from SMP

Hello Folks,

     We have two application which are developed in SMP and one in-house mobile web application . Now users are accessing two application from SMP and other from outside. So they need a hyperlink inside SMP to access the third application as well with the same credentials. SMP application are being authenticated through LDAP. So how can pass the same credentials to access the in-house mobile application from SMP ? So user no need to login again while clicking the hyperlink. Please advise . Thanks in advance for you valuable comments.

Thanks
